摘要:

节能控制能够有效降低能耗,对保护环境等方面具有重要影响;但目前大多数电子节能控制器都是通过采用单片机技术和双向晶闸管过零触发交流调压电路对电子节能控制器进行设计;通过介绍电子的负荷特点和节能原理,分析电子节能控制器的硬件组成电路,并对电子节能控制器的主要软件程序的流程图进行设计,完成电子节能控制器设计;但这种方法节能控制效果较低,难以保证电子节能控制器性能,为此,提出一种基于模糊PID控制的嵌入式电子节能控制器设计与实现方法;首先通过对嵌入式电子节能控制器的处理器、电源电路、复位电路、系统时钟电路、JTAG接口电路、D/A转换电路、功放电路、双极性电源电路以及嵌入式电子节能控制器硬件PCB板器件布局等的设计,完成嵌入式电子节能控制器硬件设计;在此基础上,选用模糊PID控制方法对嵌入式电子节能控制器进行设计；通过分析模糊PID控制原理,介绍加入自调节因子的模糊PID控制的算法设计,以此确定输入输出隶属度函数,再利用模糊推理和模糊规则,得到电子节能控制器的模糊控制过程,从而完成嵌入式电子节能控制器的设计;实验证明,所提方法能够有效提高嵌入式电子节能控制器的节能控制效果,具有良好的使用价值。

Abstract:

Energy saving control can effectively reduce energy consumption, and has an important impact on the protection of the environment. But most electronic energy saving controllers is designed by adopting the single chip microcomputer technology and the bidirectional thyristor zero crossing triggering AC voltage regulating circuit. Through the introduction of load characteristics and the energy-saving principle of electronic circuit analysis, electronic energy-saving controller hardware and software flowchart of the main program of controller is designed. However, the energy-saving control effect is low and it is difficult to guarantee the performance of electronic energy saving controller. Therefore, a design and implementation method of embedded electronic energy saving controller based on fuzzy PID control is proposed. Based on the embedded electronic energy-saving controller processor, power circuit, reset circuit, system clock circuit, JTAG interface circuit, D/A conversion circuit, amplifier circuit, bipolar power supply circuit and embedded electronic energy-saving controller hardware board PCB devices layout design, complete the embedded electronic energy-saving controller hardware design. On this basis, the fuzzy PID control method is used to design the embedded electronic energy saving controller. Through the analysis of the fuzzy PID control principle, introduced to the self regulating factor fuzzy PID control algorithm is designed to determine the input and output membership function, then using fuzzy reasoning and fuzzy rules, fuzzy controller of electronic energy saving control process, thus completing the design of energy saving controller embedded electronic. Experimental results show that the proposed method can effectively improve the energy saving control effect of embedded electronic energy saving controller, and has good use value.
