摘　　要：针对工业过程中常见的积分时滞对象,基于内模控制结构的设计原理,提出了一种PID控制器的解析设计方法。该方法通过引入闭环系统设定点低通滤波器来减少超调,从而达到二自由度控制;系统性能可通过单参数加以调节和优化。同时分析了系统的标称性能和鲁棒稳定性。最后通过仿真实例验证了控制方案的有效性。Aiming at the commonly seen integral time delay phenomenon in industrial processes,based on the designing principle of inner mode control structure,the analytical design method for PID controller is proposed.With this method,through inputting low-pass filter for the closed-loop system set point,the overshoot is reduced to reach two-degree-of-freedom control.The performance of the system can be adjusted and optimized by single parameter.The effectiveness of the control strategy is verified through simulation of practical examples.The nominal performance and robust stability of the system are also analyzed.
