摘　　要：本文设计了温度控制系统,采用Labview语言设计的上位机PID控制,模糊PID的参数通过串口传输给下位机,下位机接收的PID参数控制输出PWM波,从而控制加热装置的功率。采用模糊PID控制,改善系统的响应度并且大大的提高系统的精度。用Labview设计的上位机界面可以方便的输入控制变量,实时显示环境温度值,使得本系统控制灵活、原理简单、应用广泛。This paper introduces the control system design of temperature,we achieve the PID control in upper computer using the language of LabVIEW,the fuzzy PID parameters are sent to microcomputer through serial port,as long as microcomputer receives the parameters it exports PWM waveform so as to control the power of the heating device.This design adopts fuzzy PID control which improves the system response degrees and greatly improves the precision of the system.We can conveniently input control variables with the interface designed by LabVIEW,which can display the temperature of environment real-time and makes the system control flexible,principle simple and application wide.
