摘要
根据文献［１］中给出的满足Ｈ∞和Ｈ２范数性能指标的内稳定控制器参数化结果，分别讨论了满足上述两种范数性能指标的同时镇定控制器参数化问题。将［１］中的状态空间参数化结果转换到频率域，并从频率域结果出发，推出同时镇定控制器中参数所应满足的一系列二次方程约束条件；给出了满足一定系统性能指标的同时镇定控制器参数化的一种方法，并用一具体算例加以说明。
Based on the results of internal stability controller parametrization given in reference ,a controller parametrizing method is introduced for simultaneous stabilization that statisfies H ∞ and H 2 norm performances. The state-space prametrizing formulas for H ∞ and H 2 suboptimal controllers in are transformed into frequency domain ones, and from these frequency domain results, a finite number of quadratic equations are derived which constrain the parameters in the simultaneously stabilizing controllers. A kind of parametrizing method for the controller that guarantees a certain design performance is proposed, and an illustrative example is given.
