摘要
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 。
The design problem of robust control systems for plants with several types of uncertainties was investigated to achieve different kinds of robust control properties. A robust control approach based on signal compensation was developed which differs from the methods based on system transfer properties or input output properties. The signal compensation method regards the influence of the plant uncertainties on the closed loop control properties as an equivalent disturbance. A robust compensator is added to the nominal controller designed for the nominal plant without disturbance to produce a robust compensation signal to reduce the influence of the equivalent disturbance. The robust controllers have evident structural meanings and the controller parameters can be easily tuned on line.
