对于具有多种类型不确定性的系统 ,研究实现不同类型鲁棒控制性能的鲁棒控制系统设计问题 ,提出基于信号补偿的鲁棒控制方法。该方法与现有的基于系统传递特性或输入输出特性的方法不同 ,它将系统所具有的不确定性对闭环系统控制性能的影响视为等价干扰的影响 ,在对标称受控对象设计的标称控制器的基础上加入一鲁棒补偿器 ,产生鲁棒补偿信号 ,抵消或抑制等价干扰的影响 ,实现鲁棒控制。该方法设计的鲁棒控制器结构意义明确 ,参数易于在线整定
For systems with many types of uncertainties, the robust control system design problem for different types of robust control performance is studied. A robust control method based on signal compensation is proposed. This method is different from the existing methods based on system transfer characteristics or input-output characteristics. It regards the influence of the system uncertainty on the control performance of the closed-loop system as the equivalent interference effect. When designing the nominal controlled object Based on the nominal controller, a robust compensator is added to produce a robust compensation signal that cancels or suppresses the effects of equivalent disturbances to achieve robust control. The robust controller structure designed by this method has definite meaning and parameters are easy to set online
