摘要/Abstract

摘要： 针对受参数不确定和负载扰动影响的直流无刷电机的鲁棒速度控制问题，采用二阶滑模控制中的超螺旋算法设计速度控制器。控制器将不连续控制作用在滑模量的二阶微分上，不但保持了传统一阶滑模的性能，而且消弱了系统抖振。仿真结果表明，算法对负载和参数的变化具有很强的鲁棒性，有效地消弱了传统滑模的抖振现象。

Abstract: The aim of this paper is to deal with the second sliding mode approach to brushless DC motor robust speed control.The main feature of the proposed scheme is the robustness against heavy motor parameters variations and load disturbances.A speed controller is designed based on super-twisting algorithm.In this strategy，the discontinuous control effects are acted on the second order differential of the sliding mode，so the chattering phenomenon can be eliminated in theory.The simulation results show that this strategy has very strong robustness against load disturbances and parameters varieties，and at the same time，the chattering is attenuated availably.

Key words: brushless DC motor, rotation speed control, second order sliding mode control, super-twisting algorithm
