Design of Boiler Temperature Control System Based on DSP and Current Loop

A design scheme of boiler temperature control system based on DSP and current loop was proposed, and designs of generator and receiver of the current loop, DSP processing module and control algorithm were introduced in details. The boiler temperature control was realized by using TMS320F2812 DSP as a controller, 4~20 mA current loop as transmission mode, and PID as control algorithm. The system has high flexibility and reliability.
