摘要: 主要研究系统具有闭环极点位置约束的H2/H∞混合控制问题.通过引人一个辅助性能 函数,将具有极点位置和H∞性能约束的系统H2性能优化问题转化成有一个矩阵方程约束 的辅助性能函数优化问题,并给出这个问题静态输出反馈解的表达式.Abstract: This paper studies the problem of mixed H2/H∞ control for systems with poles in specified region. First, an auxiliary performence function is introduced, and the problem of optimizing H2 norm of systems subjected to contraints in pole region and H∞ performance can be converted into the problem of minimization of the auxiliary performance function subjected to constraints described by a matrix equation, then this problem is solved by Lagrange multipliers, and a static output feedback controller is designed.
