摘　　要：针对离散时间系统的变结构控制问题,对常规离散变结构抖动产生原因进行分析,给出了改进的离散趋近律和滑动平面的选择方法,消除了抖振,缩短了趋近时间;提出了离散模型参考变结构控制算法,提高了系统的鲁棒性。仿真结果表明,该方法是可行的,减小了系统的抖动,并就保证了系统的稳定性。Discrete-time systems for the control variable structure of the conventional discrete variable structure causes jitter analysis, the improved discrete reaching law and sliding plane options were given to eliminate buffeting, the approach was shortened; discrete variable structure model reference control algorithm was proposed, the robustness of the system was improved. Simulation results show that the method is feasible, reduces the jitter of the system, and guarantees the stability of the system.
