Multivariable Dahlin Controller Design

摘要: 在现代鲁棒控制理论基础上,提出一种多变量Dahlin控制器多目标优化设计方法. 利用线性分解变换,多变量Dahlin控制器设计问题被转化为标准的H∞优化问题,通过对标 准的H∞优化问题求解得到了最终的控制器.它同时具有时滞补偿,解耦和控制的作用.与已 有的方法相比,该方法不但直观,而且兼顾了系统的性能和鲁棒性.Abstract: The well-known Dahlin controller for scalar control systems is extended to the control of a class of multivariable control systems with time delays. The problem of multivariable Dahlin controller design is converted to a standard H∞ optimization problem. By solving the H∞ optimization problem, we obtain the multivariable Dahlin controller. Compared to the previous method, the new one provides both good performance and robustness.
