本文介绍一种设计控制器的方法,这种控制器能够提高对缩简弹性模态的鲁棒性。这种方法包含有受频域约束的二次性能指标最小化的问题。频域判据的选择要能有效地衰减整个动力学系统的高频响应,而又要能够保持闭环系统总的性能。所得到的约束条件关系构成函数最小化的结构,并且利用参数最优化的方法求解。
This article describes a method of designing a controller that improves the robustness of the reduced elasticity modal. This method includes the problem of minimizing the quadratic performance index constrained by the frequency domain. The choice of frequency domain criterion should effectively attenuate the high frequency response of the entire dynamical system while maintaining the overall performance of the closed loop system. The resulting constraint relationships constitute the structure with minimized functions and are solved using the method of parameter optimization.
