In this paper, the stabilization problem of actuators saturation in uncertain chaotic systems is investigated via an adaptive PID control method. The PID control parameters are auto-tuned adaptively via adaptive control laws. A multi-level augmented error is designed to account for the extra terms appearing due to the use of PID and saturation. The proposed control technique uses both the state-feedback and the output-feedback methodologies. Based on Lyapunov׳s stability theory, new anti-windup adaptive controllers are proposed. Demonstrative examples with MATLAB simulations are studied. The simulation results show the efficiency of the proposed adaptive PID controllers.
本文通过自适应PID控制方法研究了不确定混沌系统中执行器饱和的镇定问题。PID控制参数通过自适应控制律进行自适应调整。设计了一种多级增广误差来考虑由于使用PID和饱和而出现的额外项。所提出的控制技术同时使用了状态反馈和输出反馈方法。基于李雅普诺夫稳定性理论，提出了新的抗饱和自适应控制器。研究了具有MATLAB仿真的示范例子。仿真结果表明了所提出的自适应PID控制器的有效性。
