Comparative Performance Investigation of Control Techniques for Solar PV Fed Induction Motor Drives

This paper provides a comparative analysis of three key control strategies for solar photovoltaic (PV) fed induction motor drives (IMDs): field-oriented control (FOC), direct torque control (DTC), and model predictive control (MPC). The study begins by examining the theoretical operating principles of each method, followed by an analysis of their control structures and implementation considerations. A comprehensive assessment is conducted to evaluate the performance of these strategies in various operating conditions, including starting response, step torque response, and low-speed operation. The comparative analysis aims to highlight the advantages and limitations of each control method when applied to solar PV-fed IMDs. This work provides valuable insights into the trade-offs between dynamic performance, steady-state behavior, and implementation complexity for each control strategy, assisting engineers in selecting the most suitable method for specific renewable energy applications.
