VSS type self-tuning control

Abstract

Discrete variable-structure control and its application to self-tuning control are considered. The proposed variable structure control does not use state variables but uses present and past output or input-output signals. Variable-structure control for the deterministic discrete-time system based on the minimum variance and generalized minimum variance control is proposed. The method is then extended so that self-tuning control is realized for the plants with uncertain parameters by identifying the control law online. A simulation study shows the effectiveness of the proposed algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
