基于控制规划的边界层滑模控制

Programming control-based sliding mode control with boundary layer

提出了一种基于控制规划的边界层滑模控制方法。在对传统边界层方法分析的基础上,通过对切换控制作用的规划设计,一个固定的边界层厚度将自动产生,在边界层内切换控制作用按照规划好的控制作用来进行调整,保证了系统可以充分利用已有的设计带宽,提高了系统的跟踪精度。针对一个二阶非线性系统进行了仿真研究,结果表明本文给出的设计方法是有效的。

A design method to programming control-based sliding mode control with boundary layer is suggested, Through analying the conventional sliding mode control with boundary layer, a fixed boundary layer thickness is produced by programming the switching control. Within the boundary layer, the programming switching control can take advantage of the system bandwidth and improve the tracking performance. The method is applied to the control of a second order nonlinear system. Simulation results verify the validity of the proposed approach.
