基于控制历史的延迟系统模糊控制及其仿真

通过对传统模糊控制器的改进，提出一种新型的适合于变延迟系统的控制方法。在对控制对象动态特性的研究的基础上，将控制历史引入控制器的决策过程，设计出了一种基于控制历史的延迟系统模糊控制器。与传统的模糊控制器相比，该模糊控制器用历史的控制信息代替偏差变化率作为模糊控制的决策依据，能够及时地反映出被控制量的变动趋势。仿真结果表明，所提出的控制方法可以明显地改善对延迟对象的控制效果，并具有较强的适应性。

Fuzzy Control for Delay System Based on Control''''s History and its Simulation

By improving the traditional fuzzy controller,a new kind of control method which is suitable for variable delay system is presented.With the study on the dynamic characteristics of control objects,a kind of fuzzy controller based on control's history was designed for delay system by introducing the control's history for the decision process of the controller.Compared with the traditional fuzzy controller,this fuzzy controller used the historical control information as the decision basis of fuzzy control instead of the deviation change rate,and it could reflect the changing trend of controlled variable.Simulation results show that this control method can improve the controlling effect of the delay objects with comparatively strong adaptability.
