| 摘 要： | 针对多变量病态过程的控制问题,提出一种鲁棒逆基控制器的设计方法。该方法把频域响应近似法(Frequency Response Approximation,FRA)和高级鲁棒控制方法相结合,采用频域响应近似法设计一个低阶逆基控制器来近似,通过高级鲁棒控制方法获得的高阶鲁棒控制器。得到的控制器结构简单,容易实现,并且具有良好的鲁棒控制性能。通过对一个在过程控制领域被广泛研究的病态精馏塔模型进行设计与仿真,验证了该方法在病态过程控制问题中的有效性。

| Abstract: | A design method for robust inverse-based controller to ill-conditioned process is introduced.The method combines frequency response approximation and advanced robust control method.The advanced robust control method is used to obtain a robust controller,and the frequency response approximation is used to design an inverse-based controller to approximate the robust one.The controller designed by this method has simple structure and good control performance.The whole procedure is simulated in a controller design for a well-known ill-conditioned distillation column model.The simulation results show the effectiveness of this method. |
