| 摘 要： | 针对一类高阶MIMO非线性系统设计了基于快速模糊干扰观测器的自适应Terminal滑模控制方案.通过设计快速模糊干扰观测器,克服了传统模糊干扰观测器在误差较小时收敛速度慢的缺点.严格证明了跟踪误差及观测误差均在有限时间内收敛到零的小区域.最后在高超声速条件下,对空天飞行器再入过程的姿态控制进行仿真,结果表明了所设计干扰观测器的优越性和闭环控制方案的有效性.

| Abstract: | A novel adaptive Terminal sliding mode control based on fast fuzzy disturbance observer is designed for a high order MIMO(multiple-input multiple-out-put) nonlinear system.To solve the shortcoming of learning slowly of traditional fuzzy disturbance observer when the approximation errors are very small,a fast fuzzy disturbance observer is designed.It is strictly proved that the tracking errors and approximation errors converge to very small regions in finite time.Finally,simulation results of ASV(aerospace vehicle) re-entry demonstrate the effectiveness of presented control scheme. |
