模糊增益调整PID控制在VAV系统中的应用

The application of PID fuzzy gain setting control technology in the VAV air-conditioning system

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KP,Ki,Kd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。

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 Kr, Ki,Kd 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.
