摘要
以单片机为模糊控制器,结合温度传感变送器、A/D转换器、LED显示器、固态继电器等,组成温湿度控制系统,将给定的温度与测量温度的相比较,得出偏差量,然后根据模糊控制算法得出控制量。执行器由开关频率较高的固态继电器开关担任,采用PWM控制方法,改变同一周期中电子开关的闭合时间。从而调节高温电磁阀开关的导通时间,达到控制蒸汽目的。
MCU fuzzy controller, the temperature sensor transmitter, ADC, LED display, Solid State Relay, a component of the temperature and humidity control system. MCU will measure the temperature and the temperature compared drawn deviation, and then come under the control of fuzzy control algorithms. For the implementation of the Solid State Relay switches from as high switching frequency, PWM, change with the closure of a cycle of electronic time. High temperature electromagnetic valve to adjust the conduction time to achieve the goal of steam control.
