摘要
采用LonWorks现场总线技术开发了智能路灯监控节点,改进了传统的模糊PID控制器结构,采用3个子模糊控制器组成一个复合模糊PID控制器,把过渡时间作为各子模糊控制器的公共输入,并采用遗传算法(GA)对复合模糊PID控制器的隶属度函数进行了离线优化,从而使监控网络的通信效率与通信质量大大提高,并实现了路灯照度随行人车辆多少自动调节。
LonWorks technique is used to tap intelligent street lamp control node. Design the structure of the classical fuzzy PID is improved, three sub - fuzzy controllers are as a composition fuzzy PID controller, the transition time is as every sub -fuzzy controller common input and genetic algorithm(GA) is used to optimize the membership functions of the composition fuzzy PID controller. At last the communication efficiency and communication quality of the control system is improved largely and the street lamp luminance self - regulation with the number of the foot passenger and vehicle is realized, saving electricity energy.
