摘要：A new optimization control method, which is based on the optimization employing Bezier curves of control variables, is proposed to improve engine thrust response performance. The minimum of the time consumption for control variables changing from start to end point is selected as objective function. Unlike conventional methods, the optimization variables are altered to the Bezier curves of the control variables in this scheme. This new acceleration optimization control only establishes one optimization problem for the overall acceleration process instead of establishing a series of sub optimization problems, which is usually adopted by conventional optimization controls. Hence, the proposed method is easier to overcome the disadvantage of the conventional ones, which just search for the optimal engine performance in local time period. Finally, for comparisons, the simulations for the proposed method and the conventional one have been both conducted. The simulations demonstrate that, al
