采用反馈的鲁棒系统设计方法

基于多变量系统鲁棒理论和反馈可以减小对象参数变化对输出影响的思想，本提出一种鲁棒系统设计方法和设计内反馈增益矩阵的算法。用该方法对一实际工业对象设计了鲁棒控制系统，结果令人满意。理论分析和实际系统设计结果表明，该方法设计的系统比串联补偿鲁棒设计的系统具有更好的鲁棒稳定性和鲁棒性能。

Design Method for Robust Systems Using Feedback

Based on the robust theory for multivariable systems and the concept that the feedback can decrease the effect of plant parameter variations on the output, this paper presents a design method for robust systems and an algorithm for designing inner feedback gain matrix. The method is applied to designing a robust control system for a practical industrial plant with satisfactory results. It is shown that, for the theoretic analysis and the design examples, the resulting system using this method exhibits better robust stability and robust properties in comparison with the robust design method using series compensation.
