一类非最小相位系统的多变量多模型解耦控制器

为解决系统暂态响应变差问题，提出一种基于多模型切换的多变量直接自适应控制器，通过加权多项式矩阵的选择，可消除稳态误差，实现静态解耦控制，该控制器由多个参数已知固定模型和两个自适应模型构成，多个固定参数控制器模型可由系统参数模型通过映射直接得到，并与邻城一起完全覆盖控制器参数模型集，仿真结果表明，对于非最小相位系统，暂态响应可得到明显改善。

Multivariable decoupling controller using multiple models for a non-minimum phase system

A multiple models direct adaptive decoupling controller is presented to improve the transient response. It consists of multiple fixed models and two adaptive models. The fixed models are mapped from the system parameter models directly and used to cover the controller parameter set with their neighborhoods.Bythe1choiceofthe weighting polynomial matrix, it not only eliminates the steady output error, but also decouples the system statically. The analysis of global convergence is given. SimulationG*1examplesillustratethatthetransient response of non-minimum phase systems is greatly improved, by using the multiple models adaptive decoupling controller.
