| 摘 要： | 针对一类不确定多输入多输出(MIMO)线性系统,提出一种全局快速终端滑模变结构控制方案.通过对系统进行特殊的非奇异状态变换,设计了相应的非线性终端滑模超曲面及变结构控制律,使得系统状态在有限时间内收敛到终端滑模面上,随后保持在滑模面上并按全局快速终端滑模规律运动,以较普通终端滑模更快的收敛速度在有限时间内到达平衡点.仿真结果证明了该方法的有效性.

| Abstract: | A global fast terminal sliding mode variable structure control methodology for a class of uncertain MIMO linear systems is proposed.By using a special kind of nonsingular state transformation,the corresponding nonlinear terminal sliding mode hypersurface and variable structure control law are designed.The system states can be driven to converge to the terminal sliding hypersurface in finite time,then retain on the sliding hypersurface and reach the equilibrium point in finite time according to the motion la... |
