摘要
探讨约束系统的降阶输出反馈控制器设计和吸引域估计问题。借助饱和函数的LDI(linear differential inclusion)描述形式,运用辅助反馈矩阵,得到了椭球集在吸引域内不变的充分条件,提出了一种具有最大吸引域的降阶输出反馈控制器的设计方法。
In the paper the design of the reduced - order output feedback controller for constrained system and the estimation of domain of attraction are discussed. In the formulation of LDI (linear differential inclusion) of saturation function, the sufficient condition is obtained, which guarantees the invariability of the ellipsoid set in the domain of attraction by using auxiliary feedback matrix. A design method of reduced - order output feedback controller with larger domain of attraction is presented.
