扇区滑动模态控制方法

A Sector Sliding Mode Control Method

本文针对传统滑动模态控制的抖振问题，提出了扇区滑动模态的概念，分析了扇区滑动模态的良好品质，并在扇区滑动模态概念的基础上提出了扇区滑动模态控制方法。理论证明和仿真结果均表明．扇区滑动模态控制能够保持传统滑动模态控制良好的鲁棒性，同时可以消除动态过程中的抖振，另外还能保证系统的稳定性及良好的动态品质。

In this paper.the concept of sector sliding mode is proposed for the chat teribg problem of traditional sliding mode control,its good dynamics is analysed,and based on the concept the sector sliding mode control is presented. The theoretical proof and simulation results show that the sctor sliding mode control can eliminate the chattering in the transient state and ensure stabilization and good dynamics for the plant,as well as maintain the good robustness of tranditional sliding mode control.
