| 中文摘要 |
| 为提高时变系统的稳定性和精度,提出了基于在线参数辨识的自适应插补控制方法.首先,采用传递函数的即约分解方法,利用Bezout等式,导出了针对时变参数系统的插补控制器,并证明了插补控制系统的稳定性.这种插补控制器还可改形为常用PI形式,以方便工程上的应用.其次,引入在线辨识方法,构造出自适应插补控制器.最后,将自适应插补控制器应用于参数时变的胶带压延机厚度控制系统中,通过仿真证明了控制的有效性. |

| To improve the stability and precision of the time-varying system,an adaptive interpolate control method based on the online parameter identification is presented.First the controller for the time-varying system was deduced according to irreducible decomposition method of transfer function and Bezout equation,and the stability of the interpolate controller was proved.The controller could also be modified to be a general PI controller for the convenience of industrial application.Second,the adaptive interpolate controller was built up with the on-line identification method.Finally,the controller was applied to thickness control system of tape rolling mill whose parameters were time-varying.The simulation results show the validity of the control. |
