摘要
讨论了一类非线性相似组合系统的基于估计状态反馈的分散控制问题。构造了非线性渐近状态观测器,并证明了状态误差按指数收敛到零。同时,给出了组合系统经估计状态向量的反馈控制可实现分散镇定的一个充分条件。
The problem of decentralised control of a class of interconnected non -linear systems, possessing a certain similarity property, via estimated state feedback has been studied in detail. A nonlinear asymptotic state observer is constructed first, and then it is shown that the state - error tends to zero exponentially. Furthermore, a sufficient condition under which the interconnected system can be stabilized via feedback con-trol on the grounds of the estimated state vector is derived.
