本文针对用普通PID控制对VAV系统控制参数难以整定的问题,设计了一种基于模糊控制原理的PID参数在线自调整控制器,根据偏差和偏差变化率来实时调整p K , i K , d K 参数。通过计算机仿真结果表明,这种模糊增益调整PID控制器比常规PID控制器有更好的控制效果,大大改善了系统的动态和稳态性能。关键词:变风量 静压 模糊增益调整PID 控制 模糊控制 仿真Abstract: Due to the current PID control is difficult in parameter tuning in VAV air conditioning system, a method of fuzzy PID gain setting control is designed in this paper , which can set the parameter p K , i K , d K ontime. Computer simulation results show that the fuzzy PID gain setting control method is superior to current PID control, and greatly improves the dynamic capability and stabilization capability.Key words:VAV;static pressure;fuzzy PID gain setting control;fuzzy control;Simulation
