摘要：

Recently, variable structure systems (VSS) control has been widely used in motor control systems. It provides attractive features such as fast response, good transient performance, insensitivity to variations in plant parameters, and external disturbances. However, the undesired phenomenon of chattering is a serious problem. In this paper, a new VSS control algorithm called chattering alleviation control (CAC) is proposed to solve this serious problem. Both analog and digital controllers using the theory of CAC are applied to the position control problem of a dc servo motor system. Comparisons of the CAC with other VSS control algorithms indicate that the chattering can be alleviated. Moreover, the input of the CAC method contains only low-frequency components, and hence, it will not excite unmodeled high-frequency plant dynamics.
