基于粒子群整定的PID算法在VAV空调中的应用

Application of Particle Swarm Algorithm for Tuning the PID in the VAV Air Conditioning

VAV空调系统是一个非线性、强耦合的大时滞系统,常规PID控制难以取得良好的控制效果,本文设计了一种将粒子群整定的PID控制算法应用于VAV空调的控制方法。仿真结果表明,新的控制方法与常规控制方法相比,控制效果良好。

The VAV Air-conditioning system is a delay system which is nonlinear and strong coupling, and the general PID control is hard to achieve excellent effect, so in this paper we design a control method which use the PSO-PID algorithm, and this algorithm is used in the VAV Air-conditioning system. Simulation results indicate that relative to the general control method, the effect is excellent.
