MAOA: A Swift and Effective Optimization Algorithm for Linear Antenna Array Design Anoop Raghuvanshi, Abhinav Sharma, Abhishek Kumar Awasthi, Abhishek Sharma, Rahul Singhal, Kim Soon Chong, Sew Sun Tiang, Wei Hong Lim Telecom, 2025 This paper presents the modified arithmetic optimization algorithm (MAOA), a swift and effective optimization algorithm specifically designed for electromagnetic applications. Its primary advantage is its ability to avoid local minima by striking a balance between global exploration and local exploitation searches. This equilibrium is maintained through three key improvements: an enhanced initialization process, a distinctive guidance mechanism for steering searches, and an additional learning phase to refine newly found solutions. This process innovation significantly boosts MAOA’s performance in addressing both constrained and unconstrained optimization challenges. In this study, MAOA is applied to optimize the spacing and current amplitude of linear antenna array (LAA) elements, with the goal of minimizing peak side lobe level (PSLL), close-in side lobe level (CSLL), and overall side lobe level (SLL), both with and without constraints on first null beamwidth (FNBW), as well as null positioning with SLL minimization. Ten designs, comprising 10 and 20 antenna elements of LAA and one 14-element circular antenna array (CAA), showcase MAOA’s proficiency in antenna array pattern synthesis. Optimizing element positions results in a PSLL of −21.28 dB, a CSLL of −34.50 dB, and a null depth of −89.00 dB, while optimizing current amplitude achieves a PSLL of −24.32 dB, a CSLL of −29.73 dB, and a null depth of −77.60 dB across various antenna designs. Simulation results reveal that MAOA significantly surpasses traditional uniform linear arrays (ULA) and established optimization techniques. Its superiority is further confirmed through a Wilcoxon rank-sum and Friedman test.
Linear Antenna Array Pattern Synthesis Using Multi-Verse Optimization Algorithm Anoop Raghuvanshi, Abhinav Sharma, Abhishek Kumar Awasthi, Rahul Singhal, Abhishek Sharma, Sew Sun Tiang, Chin Hong Wong, Wei Hong Lim Electronics Switzerland, 2024 The design of an effective antenna array is a major challenge encountered in most communication systems. A much-needed requirement is obtaining a directional and high-gain radiation pattern. This study deals with the design of a linear antenna array that radiates with reduced peak-side lobe levels (PSLL), decreases side-lobe average power with and without the first null beamwidth (FNBW) constraint, places deep nulls in the desired direction, and minimizes the close-in-side lobe levels (CSLL). The nature-inspired metaheuristic algorithm multi-verse optimization (MVO) is explored with other state-of-the-art algorithms to optimize the parameters of the antenna array. MVO is a global search method that is less prone to being stuck in the local optimal solution, providing a better alternative for beam-pattern synthesis. Eleven design examples have been demonstrated, which optimizes the amplitude and position of antenna array elements. The simulation results illustrate that MVO outperforms other algorithms in all the design examples and greatly enhances the radiation characteristics, thus promoting industrial innovation in antenna array design. In addition, the MVO algorithm’s performance was validated using the Wilcoxon non-parametric test.
Unified Dual-Wheel PID Control for Differential Drive Robot with Distinct Wheel Error Functions Yogi Naragani, Deepak Singh Gariya, Rahul Singhal 2024 10th Indian Control Conference Icc 2024 Proceedings, 2024 The PID controller is the most versatile controller due to its ease of implementation. However, multi-input control design with PID controller is a challenging task. This paper presents the unified PID implementation for the right and left wheels of the differential drive robot. The distinct error function was considered for each wheel utilizing the robot's kinematic relationship. The simulation result of the proposed unified dual wheel PID (UDW-PID) controller presented for the straight, circular and sine path. The control action generated for the respective wheel resulted in smoother and quicker convergence towards the path, and afterwards stable behaviour over the path.
Residual-based fault detection isolation and recovery of a greenhouse Rahul Singhal, Rajesh Kumar, Satyanarayana Neeli International Journal of Automation and Control, 2022 This paper is concerned with fault detection, isolation and recovery (FDIR) of the greenhouse whose temperature is regulated by the model predictive controller (MPC). The residual generation approach is adopted for fault detection and isolation. The new considerations in the proposed FDIR approach are the residual generation for actuator faults, regulation failure detection as the indication of inappropriate regulation by the controller, below threshold actuator fault detection strategy, and recovery operation updating model used by MPC once the FDIR isolates the actuator fault. The proposed control strategy FDIR with MPC was compared with fixed model information MPC for simulated scenarios of the actuator fault. It has been shown that FDIR successfully detects, isolates and updates model information with low computation burden for non-delayed control evaluation.
Optimizing Neural Network Hyperparameters with Swarm Intelligences for Commercial Buildings Load Classification Akshay Gupta, Rahul Singhal, Rajesh Kumar Proceedings of the 2021 IEEE 18th India Council International Conference Indicon 2021, 2021 Advanced metering systems are crucial in smart grids for analyzing collected data with high accuracy, efficient control, and planning of energy demand and supplies. Therefore, an adaptable automated process is essential for classifying different types of building loads for the smart grid to comprehend their consumption pattern. In this paper, a method is suggested for the load classification of commercial buildings to improve classification accuracy with swift execution and less computational burden, unlike deep learning techniques. Moreover, using a neural network with the optimally selected hyperparameter leads to remarkable performance as the neural network’s performance depends heavily on its hyperparameters.
Robust shortest path planning for aircraft using bounded region voronoi diagram Tanishk Dudi, Rahul Singhal, Rajesh Kumar, Ameena Al-Sumaiti, Ton Duc Do 9th IEEE International Conference on Power Electronics Drives and Energy Systems Pedes 2020, 2020 Flight safety and fuel consumption are major concerns of airline industry. En route civil aircraft may encounter hindrances such as bad weather patches, prohibited areas, and flight constraints. Robust path planning ensures maximum safety of the aircraft, crew members and passengers in unknown environment such as uncertain wind direction and drag from low pressure areas. This paper presents the robust path generation methodology near to the line of sight from starting aerodrome to the target aerodrome. This methodology confined the search space on the aerospace map to the nearby hindrance from the line of sight and then plan a robust path for the aircraft with the help of voronoi diagram. The voronoi diagram for the airspace map gives cells on the grid map, where each cell is equidistant from the hindrances. For these cells, the shortest robust path is evaluated using Dijkstra algorithm. The simulations for the shortest robust path on the airspace map were carried out for the proposed methodology and voronoi diagram for the full airspace map. The results obtained show that unnecessary clearances from the hindrances are avoided, and the computational time to evaluate the shortest robust path has been considerably reduced.
