摘要
对多输入 -多输出高阶线性定常系统从理论上详细推导出了其特征模型 ,并给出了基于特征模型的自适应模糊广义预测控制方案。所建立的特征模型为智能控制器设计和一些高阶对象的低阶控制器设计提供了理论依据 ,特别是为大型空间挠性航天器的控制提供了一种有效的途径。
For multi-input and multi-output high-order linear ordinary systems,a 2nd-order characteristic model is theoretically deduced in detail in the paper.And the adaptive fuzzy generalized predictive control scheme based on characteristic model is designed.The method on characteristic model provides a theoretical foundation for designs of intelligent controllers and the control of higher plants using lower controllers.Especially,the method provides a useful approach for the control of the large flexible spacecraft in space.Simulation results of spacecraft control verified the efficiency of the adaptive fuzzy generalized predictive controller.
