摘要:
针对工业过程控制中普遍存在的时滞现象,剖析了几种控制方法的特点,讨论了smith预估器和各种控制算法之间的联系,仿真研究了模型失配、时滞变化及干扰等因素对系统的影响.仿真结果表明:Dahlinsmith控制器和Inner Model Controlsmith控制器具有响应速度快、超调量小,特别是在模型失配情况下,鲁棒性和抗干扰能力表现得尤为突出,为系统克服纯滞后提供了途径.模型失配改进型smith结构给系统带来了良好的控制质量,对模型参数敏感度小,但有严格的限制条件.
Abstract:
Because of the universal existence of timedelay phenomenon in industrial process control, his paper analyzes the characteristics of some control methods, discusses the relations between Smith predictor and each control algorithm, and simulated studies the mismatch of model, the change of delay time and the effect of the disturbance to the system. Simulation results show that: Dahlinsmith controller and Inner Model Controlsmith controller have the advantages of fast response and low overshoot. Especially in the case of the mismatch of model, they have better robustness and stronger antiinterference ability, which provide the methods to overcome the time delay. The improved Smith predictor brings a good quality, which has little sensitivity to the model parameters but with strict restrictions.
