| 摘 要： | 提出一种固定边界的变结构控制平滑方法 ,推导出变结构控制系统的稳态误差指标与边界内部加权系数之间定量的数学关系。通过系统的稳态误差指标可以设计出固定边界的平滑方法 ,从而既消除了系统的抖振又满足了对系统稳态误差指标的要求。仿真结果验证了该方法的有效性。

| Abstract: | A new method of chatting reduction in VSS is presented. The mathematical relationship between the steady state errors and the time varying coefficients of softening method is derived. Different from the traditional trial and error method, the varying coefficient with fixed boundary can be designed through the given steady state errors, which can not only reduce the chattering in control signal but also simultaneously satisfy the specification of the steady state errors. The simulation results show the validity of the method. |
