基于 H∞ 控制理论 ,建立了结构振动系统鲁棒 H∞ 反馈控制模型 ,利用混合灵敏度设计方法 ,将鲁棒反馈控制器设计问题转化为标准 H∞ 控制问题求解。建立了一套以 TMS32 0 C30数字信号处理芯片为核心的结构振动鲁棒 H∞ 控制实验系统。通过对性能加权函和鲁棒加权函数的选取 ,取得了在指定频带上较好的减振效果
Based on the theory of H∞ control, a robust H∞ feedback control model of vibration system is established. By using the mixed sensitivity design method, the design problem of robust feedback controller is transformed into the standard H∞control problem. A set of robust H∞ control experiment system based on TMS32 0 C30 digital signal processing chip is built. Through the selection of the performance weighting function and the robust weighting function, the better vibration damping effect in the specified frequency band is obtained
