Abstract

A new discrete slide-mode controller is designed for an AC servo system according to discrete sliding-mode control theory and fuzzy control theory. The feedforward signal of the command signal is used as an average control, and fuzzy inference is used to regulate the magnitude of on-off control; system chattering is decreased effectively. Simulation study shows that an AC position servo system using this controller can realize tracking of command signals accurately, and has the ability to resist parameter distortion and reject chattering, while exhibiting good control performance.
