研究了具有执行器饱和的线性系统的输出反馈渐近跟踪问题。参考输入和干扰都表示为线性系统的零输入响应。该控制器包括内部模型与抗windup项的参考和干扰信号和状态观测器的系统，以允许输出反馈控制。整个系统被证明是渐近稳定的系统的任何初始条件下，只要参考和干扰信号的大小，使参考信号的渐近跟踪可以实现不饱和的致动器的幅度。仿真实例验证了该方法的有效性。
This paper is concerned with asymptotic tracking for linear systems with actuator saturation by output feedback control. Both reference inputs and disturbances are represented as zero-input responses of linear systems. The controller includes the internal model with an anti-windup term for the reference and disturbance signals and a state observer for the system to allow output feedback control. The overall system is shown to be asymptotically stable for any initial condition of the system as long as the magnitudes of the reference and disturbance signals are sized such that the asymptotic tracking of the reference signal can be achieved without saturating the actuator. A simulation example is presented to verify the effectiveness of the proposed approach.
