自调整模糊控制在二次调节系统中应用的仿真

Application and simulation of self-adjusted fuzzy control in the hydraulic secondary regulation system

阐述了二次调节节能系统的特点,分析了传统的PID控制器和常规的模糊控制器的不足.针对二次调节节能系统的特点笔者采用了自调整模糊控制器,并分析了自调整模糊控制器中自调整因子的确定规则.利用MATLAB的模糊逻辑工具箱设计了模糊控制器,为了缩短仿真与实际的差距,笔者利用SIMULINK环境给出了混合(连续+离散)系统的仿真模型以接近实际计算机控制.从系统输出的仿真曲线出发,对此进行了对比分析.

The characteristics of secondary regulation energy-economizing system have been given an account and the shortcomings of the traditional PID controller and fuzzy controller have been analyzed based on the former comment.In order to adapt to the characteristics of the secondary regulation energy-economizing system,the self-adjusted fuzzy controller is employed.Furthermore,the rules of the establishing self-adjusted factors in the self-adjusted fuzzy controller are analyzed.The MATLAB fuzzy logic box is used to design the fuzzy controller.In order to bridge the gap between the simulation and the actual system,the hybrid (concrete and discrete) simulation model in the SIMULINK environment is established to approach the real computer control system.Conclusions have been drawn based on the comparison of the control properties between two control methods from the point of simulation curves.
