摘　　要：为降低高效机房冷却水系统能耗,提高高效机房冷却水系统控制效果,提出一种基于改进阿基米德算法(Artificially Intelligent Optimization Algorithm,AOA)与PID的能耗优化与控制方法。方法首先构建高效机房冷却水系统能耗优化模型,并以系统能耗最低目标函数,采用引入Circle映射和莱维旋转变换策略的改进AOA算法进行目标函数求解,实现了高效机房冷却水系统能耗优化。然后构建高效机房冷却水系统被控对象模型,利用改进AOA算法优化的PID控制算法对被控对象进行控制,实现了高效机房冷却水系统控制。仿真结果表明,该方法可降低高效机房冷却水系统能耗,达到节能效果,相较于能耗优化前,优化后的系统平均能耗降低了9.88%,且改善了冷却水系统控制效果,使冷却水系统中的冷却水泵流量和冷却塔出水温度能更快达到期望流量和温度,且响应时间较快,为235s,表现出良好的控制性能。In order to reduce the energy consumption of the high-efficiency cooling water system in the computer room and improve the control effect of the high-efficiency cooling water system,a method for energy consumption optimization and control based on the Improved Archimedes Algorithm(AOA)and PID is proposed.The method first constructs an efficient energy consumption optimization model for the cooling water system in the computer room,and uses an improved AOA algorithm with the introduction of Circle mapping and Levy rotation transformation strategy to solve the objective function of minimizing system energy consumption,achieving the optimization of energy consumption for the efficient cooling water system in the computer room.Then,an efficient machine room cooling water system controlled object model was constructed,and the PID control algorithm optimized by the improved AOA algorithm was used to control the controlled object,achieving efficient machine room cooling water system control.The simulation results show that this method can reduce the energy consumption of the high-efficiency computer room cooling water system and achieve energy-saving effects.Compared with before energy optimization,the average energy consumption of the optimized system has been reduced by 9.88%,and the control effect of the cooling water system has been improved.The flow rate of the cooling water pump and the outlet temperature of the cooling tower in the cooling water system can reach the expected flow rate and temperature faster,and the response time is fast,which is 235 seconds,showing good control performance.
