In this paper, a sliding mode control system with a predictive proportional-integral-derivative (PPID-SMC) sliding surface is proposed. A robust sliding mode controller is suggested to track the desired trajectory despite uncertainty, set point variations, and external disturbances. The proposed sliding mode controller is chosen to ensure the stability of overall dynamics during the reaching ph...

This paper proposes the use of sliding mode control to improve the performance of fieldoriented speed controllers of induction motors. The integral sliding mode control provides means to obtain an accurate estimate for disturbances and plant parameter perturbations. This estimator is used as an auxiliary control loop to reject these disturbances and parameter perturbations while avoiding chatte...

This paper presents the optimal regulator for a linear system with state delay and a quadratic criterion. The optimal regulator equations are obtained using the maximum principle. Performance of the obtained optimal regulator is verified in the illustrative example against the best linear regulator available for linear systems without delays.
