中文摘要
      为了推广模糊控制器在非线性系统的应用, 提出一种利用PID控制器的参数优化和调节模糊控制器的新型设计方法. 通过模糊控制器的结构分析建立与PID控制之间的精确解析关系之后提出基于PID控制增益因子的模糊控制器设计算法, 然后利用改进的变论域思想进一步优化模糊控制器设计参数. 将其应用于暖通空调(HVAC)系统的节能控制中并与常规PID控制器相比较, 仿真和实验结果表明这种模糊控制器具有超调量小、跟踪迅速、鲁棒性强等优越的控制性能.
英文摘要
      In order to extend the application of fuzzy controller to nonlinear systems, a new fuzzy control strategy converted directly from the PID controller is proposed. The mathematical relation between the parameters of the fuzzy controller and the linear gain of the conventional PID controller is derived based on the structure analysis of fuzzy controller. Based on this mathematical relation, the fuzzy controller is designed through the gain-tuning in the PID controller. Furthermore, the improved variable universe method is employed to optimize the parameter tuning of the fuzzy controller on line. This new fuzzy controller is also applied to energy-saving control in heating, ventilating, and air-conditioning(HVAC) systems. The comparison of the simulation results between this fuzzy controller and the conventional PID controller shows that this fuzzy controller is effective and the algorithm provides less overshoot, shorter setting time and better robustness, etc.
