Abstract:To obtain a high dynamic response and high precision control of the electric servo system under unknown disturbance, a multi-mode composite control algorithm based on time-optimal control and sliding-mode control is proposed. In this control algorithm, the available range of time-optimal control and sliding-mode control are elaborated in detail through the analysis of precise dynamic model and feature model of the electric servo system. The simulation results of this control algorithm are also verified. The results show that the proposed multi-mode composite control can effectively improve the dynamic-response speed and steady-state accuracy of the electric servo system and can realize reliable and stable operation under unknown disturbance.
