Firstly, a reduced order model of this flexible structure is obtained by frequency domain identification, then unstructured uncertainties constituted by neglected modes are taken care of in the time of design process by choosing appropriate weighting functions, arid finally a robust feedback controller is designed based on the reduced order model and the approximate knowledge of unmodeled uncertainties
首先通過頻域辨識得到柔性結構的降階模型，而剩餘高階模態構成的非結構不確定性，通過對權函數的選擇在設計階段就加以考慮，然後基於降階模型和未建模不確定的近似特性設計了魯棒反饋控制器。 -
This paper presents a new method for designing robust h control system, in which the design objectives are converted into the inequality constraints and the selection of weighting functions in h controller design is expressed as a multi - objective optimization problem. the h controller, which satisfies given frequency - domain and time - domain performance indexes, can be found by using genetic algorithm ( ga ) to optimize the weighting functions
本文提出了一種基於遺傳演算法的h控制系統設計方法，把控制系統的多個設計目標轉化成不等式約束，將h控制器設計中加權陣的選取表示成一個多目標優化問題，通過遺傳演算法優化加權陣參數，進而找到同時滿足給定的頻域和時域性能指標要求的h控制器。 -
