Digital PID applied in high-precision HPCT（High-precision current transducer） based on Digital Signal Processor（DSP） TMS320F2812 and special D/A converter was researched . By using increment style PIE） Control algorithm, the stability and precision of high-precision HPCT output voltage is improved. On basis of deeply analysing incremental digital PID, the scheme model of HPCT is proposed, the feasibility simulation using Matlab is given. Practical hardware circuit verified the incremental PID has closed-loop control process in tracking HPCT output voltage.
