In order to compensate the disturbance of lathe with constant linear velocity and improve the peeling variable speed feed system for log -core veneer quality of veneer, a closed loop control method based feedforword and proportion feedback is designed in this paper. In this scheme, the kinematic model is taken into consideration, the proportion factor is optimized online by genetic algorithm to enhance the adaptability of controller and facilitate the adjustment of control parameters. The structure of this control method is simple, its stabilization time is short and its accuracy is high. The effectiveness of this method is proved by the simulation result.
