摘　　要：智慧城市建设过程中,现有城市道路路灯照明系统普遍存在智能化程度低和能源浪费大等问题,而受道路环境照度、车流量情况和其他干扰因素影响,实际路灯照明系统可视为一个复杂的多变量非线性时变模型.为解决系统的实时优化控制问题,提出了一种基于烟花算法-自适应模糊PID的LED路灯智能控制方法.采用的控制策略为自适应模糊PID,并用烟花算法在线优化PID控制器的初始参数(K p、K i和K d)和模糊控制器的隶属度函数参数.阶跃响应仿真分析表明,与现有模糊PID控制方法相比,改进方法后超调量更小(为6.2%)和响应速度更快(上升时间为0.056 s).以傍晚至次日清晨期间某城市道路支路上的10盏LED路灯为对象进行能耗测试.实验结果表明,与普通路灯控制方法相比,此控制方法可节约14.2%的电量.这一方法满足了路灯控制系统的稳定性、快速性和准确性方面要求,有效降低了城市道路照明能耗并提高了路灯使用寿命.In the process of smart city construction,the existing streetlamp lighting system has the disadvantages of low intelligence and high energy consumption,etc.Affected by the environment illumination,traffic flow and other disturbance factors of urban road,the actual streetlamp lighting system can be regarded as a complex,multivariate,nonlinear and time-varying model.In order to realize the real-time optimal control of this system,an intelligent control method of LED streetlamps based on the integration of fireworks algorithm and adaptive fuzzy PID is proposed.The adopted control strategy of the controller is adaptive fuzzy PID,and the initial parameters(K p,K i,and K d)of PID-controller and the membership function parameters of the fuzzy controller are optimized by the fireworks algorithm online.The step response simulation analysis shows that compared with the existing fuzzy PID methods,the improved method has smaller overshoot(6.2%)and faster response speed(rise time is about 0.056 s).Finally,an energy consumption test is carried out on 10 LED streetlamps on a branch road from evening to early morning.Test results indicate that the new streetlamp control method can save 14.2%of the electricity consumption.It meets the requirements of stability,rapidity and accuracy for street lighting control system and effectively reduces the energy consumption of urban road lighting and significantly prolongs the service life of streetlamps.
