  • Maximum sensitivity-based PID controller cascaded with 2/3 order filter for integrating processes with time delay
    K. Divakar, Muni Reddy G., N.M.G. Kumar, M. Ijaz Khan
    Results in Control and Optimization, 2025
    In the chemical industry, integrating processes are often encountered. Examples of integrating processes include bottom level control of a distillation column, level control of a tank with a motor fixed at the outlet, current-controlled DC motor, fermentation reactors, spacecraft take-off dynamics, paper industry drying processes, continuous stirred tank reactor (CSTR) with exothermic reactor, and so on. This article describes a new PID controller with a 2/3 order filter for integrating processes with time delay. Time delay is approximated to ratio of two polynomials using a second-order Pade’s approximation. A set point filter is used to minimize overshoot and the settling time of servo responses. Simulation studies are conducted on some of the benchmarking process models utilized in the literature. The comparative assessment is based on various performance indices.

  • Hexagon hysteresis current control-based STATCOM for grid connected wind turbine system
    G. Muni Reddy, T. Gowri Manohar
    International Journal of Power Electronics, 2020
    The use of renewable power sources, like wind power, has been increased recently due to climatic changes caused by fossil fuels and fast depletion of fossil fuels. This has lead to the tremendous increase in the interconnection of wind turbines to power system grid. This interconnection of wind turbines on a large number in grid causes problems such as power quality, maintaining system voltage, reactive power compensation, control of grid frequency and aspects of power system grid stability. In this paper, STATCOM utilises hexagon hysteresis current control (HHCC) to improve the power quality. The proposed control scheme supplies the required reactive power to the system and thus, relieves the source, leading to unity power factor (UPF) at the source and also, it injects currents to reduce THD to satisfy IEC standard. In the proposed HHCC, the current control has been achieved by transforming the three phase (a, b, c) system into stationary (α, β) reference frame and the complex space vector concept is employed. Further, the proposed system's dynamic response has been studied and the results have been presented.

  • Fuzzy controller based multi level inverter STATCOM for grid connected wind energy conversion system

    International Conference on Signal Processing Communication Power and Embedded System Scopes 2016 Proceedings, 2017
    The sustainable energy resources, like wind energy, for electrical energy generation is augmented due to environmental problems and the scarcity of conventional energy sources, leading to integration of large number of wind generators in to grid. Integration of large scale of wind generators in to grid presents challenges such as voltage stability, reactive power management, frequency control, grid stability and power quality. In this proposed scheme, Multi Level Inverter based Static Compensator with a battery energy storage system employs fuzzy based Controller to diminish the effects of power quality issues. The proposed scheme for the grid connected wind energy conversion system is simulated using MATLAB/SIMULINK The efficacy of the proposed control scheme is, it takes care of the reactive power requirement of the load and the induction generator, thus improving the source side power factor and also there will be a discernible reduction in the Total Harmonic Distortion. Using Multi Level inverter based STATCOM, lower source current distortions shall be obtained, when compared to conventional two level inverter based STATCOM Further the use of fuzzy controller for the proposed system shall reduce source current distortions.
