摘要
针对工业中常见的具有积分和时滞特性的二阶过程对象,根据鲁棒控制H∞性能指标提出了一种解析设计PID控制器的新方法,并给出了闭环控制系统保证内稳定的充分必要条件.通过在闭环系统给定点设置低通滤波器来达到二自由度控制,从而优化闭环系统的标称性能.通过仿真实例验证了该方法的优越性.
A new analytical design method of PID controller was proposed for typical second-order integrating processes with time delay in industry according to the robust control H∞ performance specification. And the sufficient and necessary conditions for holding internal stability of the closed-loop control system were provided. By introducing a low-pass filter to the closed-loop system setpoints, two-degree-of-freedom control is obtained for optimizing the closed-loop system nominal performance. At last, simulation examples were included to demonstrate the superiority of the method.
