摘要
对建筑电气设备进行PID节能控制,可以解决电气超调量大、振荡及控制精度不高的问题。在进行PID节能控制时,为了获取最佳的控制效果,需要对PID控制器参数进行自适应整定。传统的基于补偿器控制算法容易产生外电场,使建筑电气设备受到干扰,无法对其控制参数进行在线调整,降低了建筑电气设备节能控制精度。现提出一种自适应模糊PID节能控制方法,将其应用于建筑电气设备的节能控制中,将模糊控制系统和PID控制器结合在一起组成自适应模糊PID控制器,绘制其结构图,通过模糊控制对PID控制器的参数进行自适应整定。分析了PID节能控制参数整定原则,依据PID参数整定原则对PID参数的模糊控制规则进行设计,将三角形函数作为隶属函数,给出PID参数自适应整定的详细过程,获取参数的精确调整值,将其输入PID控制器中,输出的即为节能控制结果。通过节能控制性能比较分析和抗参数失配能力比较的仿真证明,所提方法具有很高的节能控制性能和抗参数失配能力。
An energy - saving control method with self - adaption fuzzy PID is proposed and applied to the energy - saving control of architecture electric equipment. Firstly, the method integrates the fuzzy control system with PID controller to constitute the self - adaption fuzzy PID controller and draws its structure chart. Then, the self - adaption adjustment is achieved to PID controller parameter through fuzzy control, and the adjustment principle of PID energy - saving control parameter is analyzed. Moreover, the fuzzy control rule of PID parameter is designed according to the PID adjustment principle, and the process of PID parameter self - adaption adjustment is given out in detail to obtain the precise adjustment value of parameter by using the triangular function as membership function. Finally, the precise adjustment value is inputted into the PID controller and the outgoing results are the energy - saving control result. The simulation results show that the method has high energy - saving control performance and good ability to resist parameter mismatch.
