| Abstract: | A novel reaching law of variable structure control for multi-Varriable system was put forward in this paper.The influence of parameters in the reaching law for dynamic performance of systems was analyzed.The physical realization of parameters was discussed,and the simplified formula of reaching time was given.The simulation results of different reaching laws for some dual input system showed that this novel reaching law could make the system quickly entering into the sliding mode and restrain chatter effect... |
