摘要
提出一种符合高氏6个特点的离散变结构控制的趋近律.应用该趋近律设计的变结构控制系统,可保证系统在有限步到达准滑模带,系统运动最终趋于原点,并有降低抖动及保持快速趋近的品质.仿真结果说明了该方法的可行性和有效性.
A discrete reaching law which accords with. the ＂six character＂ given by Gao Wei-bing is presented. The variable structure control system designed by using tb.is reaching law not only can reach the region of quasi-sliding mode in finite pace, but also can decreasingly approach to zero, and the system chattering is decreased and fast reaching speed is kept. The simulation results sb.ow the effectiveness and feasibility of the proposed method.
