| 摘 要： | 针对具有控制输入不灵敏区及有界不确定性的非线性系统,采用增益调度变结构控制策略,研究其镇定问题.利用增益调度策略和自适应参数估计方法,在同时存在参数、结构及干扰的不确定性和未知控制输入不灵敏区的情形下,提出了新的增益调度自适应变结构镇定控制律设计方法,既节省了控制能量,又消除了控制信号的颤振.所提出的控制律可以保证闭环输出为一致终结有界,并且算法比较简单,便于实现.用数字仿真方法验证了所得控制律设计方法的有效性.

| Abstract: | The tracking control for a class of nonlinear systems with unknown dead-zones and norm-bounded uncertainties is studied. To deal with structural and parametrical uncertainties, unknown disturbances and unknown dead-zones, we propose a new variable-structure controller based on the adaptive control method and the control approach of gainscheduling. The controller ensures the closed-loop system output to be ultimately asymptotically bounded. Simulation results confirm the satisfactory performance. |
