Design and System Simulation of Sliding Mode Controller of Variable Structure for Brushless DC Servomotor

介绍了无刷直流电动机驱动装置滑模变结构控制的原理和设计方法,通过数字仿真表明;滑模变结构控制器具有健全的控制性能,它对负载时参数的变化以及外界干优的影响并不敏感,系统的状态将按预定路径变化,因而控制系统具有高稳定性、高精度、坚固性和快速响应等优点.

This paper presents the principle anddesign of servoposition control drive with sliding modecontroller of variable structure. Digital simulation showsthat sliding mode controller has robust performance ofcontrol. It is unsensitive for change of parameter and disturbance. The systera state is constrained to a predetermined path in statespace. The control system has highstability,high accuracy, robust, no overshoot in the posi-tion response and minimum response time etc.
