FPGA-Based Research on the Constant Temperature Control System of Air Source Water Heater
Abstract:
In this paper, a kind of constant temperature control system of air source water heater will be shown, which is mainly consist of FPGA, temperature sensor, cold and hot water electromagnetic valve, and the parts setting temperature and displaying real-time temperature. FPGA is used to implement PID algorithm and produce PWM wave to control the rotation rate and finally adjust the opening of regulating valve. The experiments show that FPGA has a very good real-time performance and reliability in constant temperature control system.
