VSS-Type Self-Tuning Control-ß Equivalent Control Approach

This paper is concerned with the discrete-time variable structure control and its application to self-tuning control. The proposed variable structure control is designed by using the pulse transfer function. In the first, the variable structure control for the deterministic discrete-time system is proposed based on the generalized minimum variance control. In the next, the proposed method is extended so that self-tuning control is realized for the plant with uncertain parameters by identifying the control law on-line. The simulation study shows the effectiveness of the proposed algorithm.
