基于 PID 模糊控制的中央空调节能群控系统研发

摘要

We made a research of fuzzy control and PID controller combined,and put it to the central air-conditioning energy-saving group control system.Control strategy for the central air-conditioning energy-saving group control there is imperfect,resulting in equipment easily tired,and poor air capacity.The fuzzy theory was applied to the PID control technology to build the optimization strategies that aimed at main components of the central air-conditioning,and achieve the group control intelligent processing. It turns out,the program can effectively reduce operator workload,increase the adaptive capacity of the central air-conditioning,and reliable,and to achieve the objectives of energy efficiency and enhanced use of effects.%　　对模糊控制技术与 PID 控制器相结合，并在中央空调节能群控系统中的应用进行了研究。针对目前中央空调节能群控方面存在着的控制策略不完善，造成设备易疲惫，空气容量较差等问题，将模糊理论应用于 PID 控制技术，构建以中央空调主要部件为对象的优化策略，实现了群控智能化处理。事实证明，该方案可以有效降低操作人员的工作量，提高中央空调的自适应能力，且运行稳定可靠，达到了节能和增强使用效果的目标。
