摘　　要：The functional range of actiyator of diesel engine used in bulldozer was limited when the load of bulldozer was heavy, inconstancy and in the condition of fine working. For this reason the engine rotary speed controlling system consisted of digital controller and proportional actuator was applied; to meet the needs of high controlling precision requirement the online system identification for the engine rotary speed controlling system was carry out;Based on the result of system identification the control parameter PID was optimized. Test study proved that this engine speed controlling method have an excellent speed controlling performance.The functional range of actiyator of diesel engine used in bulldozer was limited when the load of bulldozer was heavy, inconstancy and in the condition of fine working.
