摘要 

以具有时滞特性的暖通空调为被控对象,将Smith预估控制算法与自适应算法结合,以李雅普诺夫稳定性理论为基础推导自适应律,设计出Smith自适应辨识器,从而实现控制器参数的自整定,并解决了控制过程中的参数时变问题,控制效果得以优化。实验仿真结果表明,Smith自适应辨识器控制算法优于常规Smith预估控制算法。

Abstract: 

Taking the HVAC with time delay characteristics as the controlled object, the Smith predictive control algorithm and the adaptive algorithm are combined, and the adaptive law is derived based on Lyapunov's stability theory, and the Smith adaptive identifier is designed, so as to realize the self-tuning of controller parameters, and solve the problem of parameter time-varying in the control process, and the control effect is optimized. Experimental simulation results show that the Smith adaptive identifier control algorithm is better than the conventional Smith predictive control algorithm.
