Aiming at the double-rotor civil turbofan engine, the acceleration controller design based on rotor acceleration is studied. By using the conventional PI controller structure, a design method that satisfies the requirements of the structure for the required rotor acceleration command is given and the solving process of PI control parameters is transformed into a constrained nonlinear optimization problem. By using the pattern search Algorithm solution. The closed-loop control loop of turbofan engine including steady-state controller and accelerator controller is built for accelerated process simulation test. The results show that the designed accelerator controller meets the performance requirements of turbofan engine accelerating process, and has certain reference value for engineering design and application.
