| 摘 要： | 考虑了带系统参数扰动的非线性时变系统的变结构控制的设计问题.首先,给出了一个状态决定的微分Ricatti方程,在一定的假设条件下,该Ricatti方程可解;其次,由此Ricatti方程的解,设计出系统的滑动区域,在此滑动区域内,给出系统的控制律,在滑动区域外,此控制律在有限时间内将系统轨迹拉入滑动区域,而在系统之外,此...

| Abstract: | This paper considers a design method of nonlinear time-variant variable structure control system with uncertainty and parameter perturbation.First,a state-dependant differential Ricatti equation(SDDRE) is given,and then a sliding sector is designed with the solution of this SDDRE.Using the sliding sector,a control law is designed such that the system state enters the sliding sector in finite time,and outside the sliding sector the system can be stabilized globally with the control law. |
