| 摘 要： | 利用有理函数逼近纯滞后，针对一类典型不稳定对象推导了ＰＩＤ控制器整定公式，与经典鲁棒控制设计方法不不是利用控制对象互质分解，而是根据闭环系统稳定性的束寻找满足要求的控制器集合，通过对最优灵敏度函数求解，解析地推导出ＰＩＤ控制器的结构和参数，得到的结果非常简单。

| Abstract: | By utilizing rational approximation,a PID controller was designed fora class of unstableprocess with time delay.Instead ofcoprime factorization the controller was parameterized based on theclosed loop constraints of internal stability. A novel design procedure was developed by minimizing the sensitivity function and the parametersofthe PID controllerwere derived analytically.The simulations were provided to illustrate the new method. |
