针对具有L2扰动的离散时间系统，提出了一种非线性抗扰动控制器的设计方法。该控制器由一个增益预定反馈控制律和一个标准观测器组成。该增益调度控制律具有由单个调度参数内插高增益控制律和低增益控制律的结构。基于观测器估计的状态变量信息，通过求解凸优化问题在线计算调度参数。结果表明，利用所提出的控制律，既可以获得较大的吸引域，又可以获得较高的干扰衰减性能。
We propose a design method of a nonlinear anti-windup controller for discrete-time systems subject to l2 disturbances. The proposed controller is composed of a gain-scheduled feedback control law and a standard observer. The gain-scheduled control law has a structure that a high-gain control law and a low-gain control law are interpolated by a single scheduling parameter. The scheduling parameter is computed on-line by solving a convex optimization problem based on the information of the state variables estimated by the observer. We show that, by using the proposed control law, both a large region of attraction and high distubance attenuation performance can be achieved.
