摘要
对一类不确定非线性系统提出了一种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饱和特性宽度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宽度变化的饱和特性,从而既减小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。
This paper presents a VSC scheme for a class of nonlinear systems. The mathematical relationship between the steady-state errors and the width of saturating property is presented. The saturating property with varying width can be designed through the specification of the 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 prove the validity of the method.
