摘要
对高为炳先生提出的离散时间系统变结构控制的趋近律进行改进,提出了系统状态在进入准滑动模态带内和带外分别采用不同趋近律的分段式趋近律,该趋近律符合高氏关于离散变结构控制到达条件的6个特点,采用该趋近律设计的系统运动最终趋近于原点,从而具有快速趋近和降低抖振的品质。仿真结果说明了该方法的有效性。
A discrete piecewise reaching law which approach to improve the discrete reaching law by Gao Wei-bing is presented.The piecewise reaching law is different while system state is in or out the quasi-sliding mode delt.This reaching law is accord with the ＂six character＂given by Gao Wei-bing,the variable structure control system designed by using this reaching law can decreasingly approach to zero,and the system chattering is decreased and fast reaching speed is kept.The simulation results show the effectiven of the proposed method.
