具有不确定项的高阶非完整系统的反馈控制问题的研究

Study of Feedback Control for High Order Nonholonomic Systems with Uncertain

针对一类具有不确定性的高阶非完整系统,通过引入观测器,采用状态-输入转换、反推方法,设计了反馈控制器.同时为了处理初值为0的情况,提出了一种新的基于第一个子系统输出值的切换控制策略,提出的切换控制策略能有效的防止系统的状态发生有限时间逃逸现象.

This paper deals with the feedback control problem for high order nonholonomic systems with uncertainties. The state-input scaling technique and back-stepping approach are used to design the output feedback controller. In order to make the state scaling effective, a new switching control strategy based on the output measurement of the first subsystem is employed.
