Abstract :
The induction motor speed control systems with multi-variable, nonlinear and strong coupled is considered. The modeled system is divided into two second-order nonlinear subsystems including the angular speed subsystem and the rotor flux linkage one. The non-singular terminal sliding mode (NTSM) control scheme with finite time convergence is used to the design of the controller. The global stability of the system is guaranteed and the system states can accurately track the reference signal in finite time. Simulation result shows the effectiveness of the control scheme and the good static and dynamic performance by using the proposed method.
