An optimum design method of acceleration and deceleration control schedule for gas turbine engine was proposed. Based on the engine transient state performance model

the transient state control schedule was optimized by changing the independent variables describing engine transient state performance of the nonlinear model in terms of the constraints. An example of the optimal acceleration control schedule for a dual axial mixed exhaust turbofan engine with different restrictions during accelaration was designed by using this method. The control schedule was verified by putting back into the engine transient state performance model. Overall relative optimize error is in order of 0.1‰. The results show enough accuracy and easy use of this method.
