Aiming at the requirement of fast response and no overshoot in the control system of an electric steering engine in an single channel rotating projectile, a high speed electric steering engine control system based on a signalloop servo architecture is designed, which is implemented by using a TMS320F2810 control chip with floating point calculation for processing AD signal and generating PWM control signal, and using compound PID control algorithm to achieve fast response and stable following. The result shows that the control system achieves the controlling requirement of the single channel rotating projectile，which can follow control signal fast and stably with high robustness.
