基于H2与H∞指标的“动中通”伺服系统控制器设计
"Satcom on move" servo system controller design based on H2 & H∞ index
摘要
Abstract
This paper studied the control design based on the H2 & H∞ index by taking the "satcom on move" servo system as the object.In terms of the feedback controller,it integrated the extended state feedback and state observer design satisfying the LQ optimal criterion into a H2 design problem,and then gave the theoretical derivation and design method.In terms of the feedforward controller,it transformed a proper disturbance suppression H∞ index into the model matching design,and gave an effective solving method.Then considering the influence of the main resonant modes and uncertainties of the system,it gave a parameters tuning specification,which enabled the system to achieve both good dynamic performance and enough robust stability margin.The design scheme from the feedback to the feedforward are focused on the disturbance suppression ability,and has achieved good results in the actual system,which can be of guidance for the controller design that requires higher disturbance suppression capability.关键词
