Abstract: In order to meet the request for a certain missile turbojet engine that it should start in a large airspace under windmilling condition, the localization of the control system’s old control plan of the engine was analyzed and a new control plan was brought forward in this paper by dint of introducing a additional control input parameter. According to the new control plan, a control law of the turbojet engine was investigated and designed. Through the result of validate test on ground bed and simulated altitude and Mach number test, it showed that the demand of starting and acceleration in a large airspace under windmilling condition for the engine was satisfied. So it can be said that the new control plan is feasible for the engine, and it was succeeded in designing a control law for the digit electronic control system of a certain turbojet engine at the first time.
