Abstract :
A synchronous reluctance motor (SynRM) driven by a Lyapunov second method is presented in this paper. We derive a control law that, control the speed and current of SynRM. The speed and current errors are used to form, a Lyapunov function. The controller approach compensates the uncertainties which occur in the control system. However, the uncertainty is difficult to obtain in practical applications. Therefore, the adaptive law is derived to adapt the value of the uncertainty in real-time. With the proposed controller, the system has a fast response and a good disturbance rejection capability. Simulation results show that the proposed controller is valid for the synchronous reluctance motor
