摘　　要：为了改善空调房间温度控制的效果,设计了PID控制器对送风温度、空调房间的温度进行实时控制,并采用时间和误差的绝对值乘积的积分(即准则)作为系统优化的目标函数,在MATLAB软件平台设计出了单纯形寻优程序对PID控制器参数进行优化。仿真结果和分析表明,单纯形搜索法在PID控制器参数优化过程中是适用的,改善了空调系统的控制效果。A PID controller was designed for real- time control over air supply temperature and air- conditioned room temperature with the integral of product of time and absolute value of allowance as the objective function of system optimization to improve temperature control of an air-conditioned room. In the process, the PID controller parameters were optimized via a simplex optimization program written on the MATLAB platform. The simulation result and analysis shows that the method is applicable to the optimization of PID controller parameters and able to improve the control of air-conditioning system.
