摘要
Abstract
A high⁃precision temperature control experimental system based on microcontroller STM32 was designed,whose temperature range is from 15 ℃ to 130 ℃. The system contains four modules of temperature measurement,control,man⁃ma⁃chine interaction and heater. DS18B20 temperature sensor is used to detect temperature. single⁃chip microcomputer STM32F429 with ARM Cortex⁃M kernel is taken as the key control unit. TFT screen is adopted in the human⁃computer interaction part to realize temperature real⁃time display. The heater is driven by pulse width modulation(PWM)wave. The system can implement the functions of transmission,control,data storage and analysis of detected temperature. The adaptive fuzzy PID algorithm is ad⁃opted to realize the on⁃line correction of three control parameters. It is unnecessary to establish accurate model for the controlled object to guarantee the power control requirements of the heater,realize the fast⁃response and stable dynamic performance. The experimental results has proved the practicability and validity of the method.关键词
