中文摘要 |
对一类含有负载扰动的离散时间线性系统研究了多控制器自适应控制问题. 建立了能够改善扰动响应的二自由度极点配置控制器集合. 证明了度量无关的滞后切换逻辑经有限次切换后可将镇定控制器锁定在控制回路
中, 保证输入输出序列有界, 因而实现对负载扰动的抑制. 算例仿真表明了该算法的有效性. |
英文摘要 |
The multi-controller adaptive control is studied for a class of discrete-time linear systems with load disturbance. Multiple pole-placement controllers with 2-DOF which can improve the response to the disturbance are developed to form a candidate controller set. It is proved that after a finite number of switching, the scale-independent hystereticswitching logic will lock the stabilizing controller in the control loop, guaranteeing that the input and output sequences are bounded and the disturbance attenuation is achieved. The simulation example confirms its efficacy. |
