摘　　要：针对不稳定时滞过程提出了一种二自由度控制系统,不仅将输入响应与干扰响应解耦,更重要的是结合了Guillermo等提出的镇定PID控制器理论以及内模控制方法,能够对时滞常数与不稳定时间常数之比小于2的对象进行有效的控制.仿真结果证明了该系统的有效性.The system can decouple load disturbance from the setpoint response. More importantly, by combining the theory on stabilizing Proportional-Integral-Derivative (PID) controller proposed by Guillermo et al. with Internal Model Control (IMC) method, the process in which the ratio of time delay to unstable time constant is smaller than two can be controlled effectively. Simulation examples are given to show the performance of the method.
