PID-Based Nonlinear Sliding Mode Control For Speed Regulation in Induction Motors: A Comprehensive Survey and Analysis

Recently, both houses and factories have been using induction motors more and more frequently. The advancement of variable speed drives is outstanding and admirable. Induction motors are becoming more and more used in a range of industries, especially those that require precise speed regulation and lightning-fast reactions, due to their longevity and minimal maintenance costs. The most important thing is to regulate speed in order to have the best torque and economy. Because of its excellent performance induction motor, the squirrel cage induction motor has found significant use in numerous fields. Steady-state errors or sluggish reaction times to changes in load are features of conventional PID controllers. This research presents a hybrid sliding mode and PID controller to optimize the performance of the control of induction motors. The PID controller is used to control the speed of the rotor, while the sliding mode controller is used to control the motor’s torque and flux.
