Implementation of FPGA-Based Neural Network Controller for Reducing Speed Ripple for a PMSM-Driven EV Using MRAS Speed Estimator
Sanjay Kumar Kakodia, Giribabu Dyanamina
IEEE Transactions on Artificial Intelligence, 2026
The conventional model reference adaptive system (MRAS) employs a proportional-integral (PI) controller with a low-pass filter (LPF). However, the LPF and integrator add phase delay and DC drift, leading to inaccurate speed estimation. Furthermore, conventional MRAS suffers from poor speed estimation owing to the initial value of the integrator and the DC drift problem. In the proposed stator-current MRAS, the measured current from the reference model and the estimated current from the adaptive model were compared. A modified integrator (MI) was proposed that eliminates the initial value and reduces the DC drift problem during the practical implementation of an integrator. For accurate speed estimation and LPF elimination, this study proposes an artificial neural network (NN) controller as an adaptive mechanism of the MRAS (NNMRAS) speed estimator for the closed-loop control of permanent magnet synchronous motors (PMSMs) in electric vehicles (EVs) during the limp-home mode. For validation, the conventional MRAS (CMRAS), modified integrator-based MRAS (MIMRAS), and NNMRAS speed estimators for direct torque and flux control (DTFC) and space vector modulation-DTFC (SVM-DTFC) were used with standard parameters, such as standard deviation (SD), overshoot, and undershoot, at different reference speeds. A laboratory test setup using a 2.2 <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">kW PMSM and the field-programmable gate array (FPGA)-based WAVECT WCU 300 controller was used to validate the effectiveness of the limp-home mode control.

Real-time implementation of the fuzzy logic controlled parallel protection technique to enhance the DFIG system's fault ride through capability
Aftab Ahmed Ansari, Giribabu Dyanmina
Scientia Iranica, 2025
A hybrid strategy is proposed in this paper for wind energy systems with doubly-fed induction generators (DFIGs) to operate continuously in the event of power fluctuation and fault-related complications in order to accept significant penetration of wind energy conversion (WEC) systems into the grid by employing a fuzzy-logic controlled modified parallel protection scheme. The scheme is designed by integrating a rotor-side series dynamic braking resistor (RSDBR) topology, a DC link brake chopper (DCBC) topology, and a rotor-side parallel resistor crowbar (REPRC) topology to suppress peak rotor currents, stator currents, and DC bus voltage at faults, thus protecting the rotor-side converter, while limiting torque fluctuations during the protection process, avoiding frequent use of crowbar short circuits, extending rotor-side converter operating time, and improving fault ride-through (FRT) capability. This research article also presents various fault overcurrent scenarios (symmetrical and asymmetrical) and provides protection analysis, including switching methods, coordination with different topologies, and resistance value calculations. The effectiveness of the proposed technique is verified using a MATLAB simulation study for a DFIG system driven by a typical 1.5 MW wind turbine. The real-time simulator (RTS)-based OPAL-RT4500 effectively verifies the operation of the scheme under various fault conditions.

Speed Ripple Reduction and Delay Compensation Using Modified Internal Mode Controller for PMSM-Based Electric Vehicle
Sanjay Kumar Kakodia, Giribabu Dyanamina
5th IEEE International Conference on Sustainable Energy and Future Electric Transportation Sefet 2025, 2025
The vector control using a cascaded structure of proportional-integral control (PI) does not provide adequate performance in disturbance or delay caused by the controller and has an overshoot in speed tracking. To mitigate the overshoot in the speed tracking profile and enhance the load rejection capability, the PI controller has been proposed with a modified integrator-based internal mode controller (MI2MC), improving the permanent magnet synchronous machine (PMSM) drive’s dynamic response. The proposed modified integrator (MI2MC) controls the integrator triggering/update time with respect to control time and thereafter updates the overall output of the (MI2MC). Further, a conventional two-level converter has high voltage stress, electromagnetic radio interference (EMI), and noise at a low speed. Therefore, the three-level neutral point-clamped converter (TL-NPC) has been investigated for the vector-controlled (PMSM) drive. The control scheme has been tested on a 2kW surface PMSM and implemented in a field-programmable gate array (FPGA)–based WAVECT-WCU300 controller.
Reduced Position Error and Overshoot Control Using Modified Integrator-Based QPR Controller and SMO for Limp Home Mode PMSM-Driven EV
Sanjay K Kakodia, Giribabu Dyanamina
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2025
The conventional sliding-mode observer used for position estimation in permanent magnet synchronous machine (PMSM) drives for electric vehicle (EV) applications experiences chattering caused by the sign function and phase delay when employing a low-pass filter (LPF). Additionally, the conventional integrator used in the proportional-integral (PI) controller suffers from DC drift and initial value problems during practical implementation, resulting in a significant overshoot and speed errors in the speed tracking profile. This study presents a modified integrator (MI) for digital implementation that eliminates the initial value problem and reduces the DC drift issue. This paper also proposes a MI-based quasi-proportional resonant (MIQPR) controller for the position sensorless control of PMSM-driven EVs using SMO. This approach eliminates the need for a sign function and LPF, thereby reducing the phase delay and effectively minimizing the position error. The proposed control scheme is experimentally validated through closed-loop control utilizing space-vector-modulation-based direct torque and flux control (SVM-DTFC). This ensures a fast dynamic response and reduces overshooting and undershooting of the speed response. The proposed method was validated through experiments conducted on a 2.2 kW PMSM and WAVECT WCU300 field-programmable gate array (FPGA) controller.
Direct Control Method for SEIG-Based WES with Fault-Tolerant Operation

5th IEEE International Conference on Sustainable Energy and Future Electric Transportation Sefet 2025, 2025
This paper proposes the Direct torque control (DTC) method using modified space vector modulation (MSVM) for three-level (3-L) back-to-back (B-B) converter to improve the transient response of self-excited induction generators (SEIG) integrated with the fluctuating speed of the wind turbine. 3-L neutral point clamped (NPC) back-to-back converters-based WES configurations with MSVM are used for controlling the torque ripples, active power, and reactive power of the SEIG-based system. The proposed configuration has been simulated in MATLAB Simulink and real-time simulator (RTS) environments. Further, the MSVM enhances the response time and reduces the oscillations at different fault situations, showing the effectiveness in both platforms.
A Reduced Switch Count Three-Level Inverter for Wind Energy System Using ANN-Based Vector Control
Navin Kumar, Giribabu Dyanamina
2025 IEEE 4th International Conference on Smart Technologies for Power Energy and Control Stpec 2025 Conference Report, 2025
In this paper, vector control with an artificial neural network (ANN) controller has been proposed for the machineside power converter(MSPC) and grid-side power converter(GSPC) for improving the power quality of the gridconnected self-excited induction generator (SEIG) based wind energy system. Further, a reduced device-count three-phase three-level switching capacitor (SC) type converter has been proposed for the grid-side converter. SC voltage helps to synchronize a five-level line voltage output. The suggested converter generates pulses using the SPWM approach. MATLAB/SIMULINK has been used to simulate the suggested model, and the WAVECT wcu300 FPGA-based controller has been used in the lab to construct the prototype model of the suggested grid-connected SEIG-based WES in order to verify its functionality In terms of reducing undershoots, overshoots, ripples, and complication in the steady state during unpredictable wind speed, the ANN with the SPWM technique beats the PI with the SPWM technique.
Enhancing Speed Response in PMSM-Fed Electric Vehicles Through Active Disturbance Rejection Controller-Based Vector Control Method
Sanjay Kumar Kakodia, Giribabu Dyanamina, Amarendra Edpuganti
2025 IEEE 4th International Conference on Smart Technologies for Power Energy and Control Stpec 2025 Conference Report, 2025
Permanent magnet synchronous machines (PMSMs) are controlled using a proportional-integral (PI) controller-based vector control scheme, which exhibits poor performance in terms of load disturbances and speed ripples. Frequent disturbances are common in electric vehicle (EV) applications; therefore, active disturbance rejection control is a promising solution. In this study, the vector control scheme incorporates the ADRC within the speed loop because the outer speed loop significantly degrades performance in response to load disturbances. Therefore, an ADRC using an extended state observer (ESO) estimates the unknown load disturbance and compensates for it, thereby making it robust. Furthermore, a MATLAB/Simulink environment using an OPAL-RT 5600 real-time simulator was used for real-time control. The effectiveness of the ADRC and PI controllers was compared by using a real-time controller with different speeds and load profiles.
