Abstract
En 中文
This paper presents a comparative study of various Proportional-Integral (PI) controller strategies applied to the speed regulation of a squirrel-cage induction motor under Indirect Field-Oriented Control (IFOC). The classical PI controller is benchmarked against three enhanced versions: the Hyperbolic PI (HPI), the Variable Gain PI (VGPI), and the Anti-Windup PI. Each controller is evaluated in terms of dynamic response, steady-state error, robustness to parameter variations and disturbance rejection. In addition, various numerical simulations under MATLAB/Simulink are carried out to evaluate the motor's performance through different operating conditions, including load disturbances and reference speed changes. The obtained numerical results conclude that, among the modified PI variants, the VGPI and Anti-Windup PI demonstrate superior performance in terms of robustness, adaptability, and transient behaviour. The obtained numerical results highlight the advantages and limitations of the control strategy, providing valuable insights for selecting an appropriate speed regulator in industrial applications.
