研究了具有幅值和连续动力学受限作动器的线性系统的稳定区域的确定问题。针对线性系统（无饱和）设计的线性动态输出反馈，研究了在尽可能大的允许初始状态区域内，保证闭环系统稳定性和被控输出约束不受约束的反卷绕设计方法。将由控制器和反卷环组成的闭环系统建模为具有死区和动力学受限非线性的线性系统，给出了LMI的稳定性条件。讨论了数值优化程序。
This paper addresses the problem of determination of stability regions for linear systems with amplitude and successive dynamics restricted actuator through anti-windup strategies. Considering a linear dynamic output feedback designed with respect to the linear system (without saturation), an anti-windup design method is investigated to guarantee both the stability of the closed-loop system and the respect of the controlled output constraints for a region of admissible initial states as large as possible. Based on the modelling of the closed-loop system resulting from the controller plus the anti-windup loop as a linear system with dead-zone and dynamics restricted nonlinearities, LMI stability conditions are formulated. Numerical optimization procedures are discussed.
