| 中文摘要 |
| 利用环路成形H∞方法对典型工业过程进行H∞设计.设计表明,典型过程的H∞控制器可表示为常用控制结构形式(如PID+滤波器),从而很容易在工程中实现.特别地,本文得到典型过程H∞控制器参数与过程常数的直接关系,因而实际中可直接使用它们得到H∞控制器而无需对每个典型过程进行H∞设计,从而方便过程控制器设计.仿真表明,本文所得H∞控制器对大时延对象有很好的控制效果,对过程常数较大变化亦有较好的性能鲁棒性. |
| 英文摘要 |
| H∞ controllers are designed for typical processes using loop-shaping H∞ approach.The results indicate that the structure of the H∞ controllers for those plants can be expressed in the usual control structue,e.g.,PID+ filter,thus can be eas-ily realized in practice. Furthermore, we obtain the direct relation between the parameters of the H∞ controllers and process con-stants,thus we can use the parametrization to set up an H∞ controller without design. Simulations show that the H∞ controller we obtained has good performance even for processes with large delay,and is robust against the variation of process constants. |
