Research on control algorithm design for aero-engine vane angle on dynamic process

This paper investigates the control law of aero-enginevane angle on dynamic process. Two kinds of corrected algorithm is presented to solve the problem of large perturbation of vane angle at the end of dynamic process. The problem is solved by using the method of slope restriction on perturbation and reducing the amplitude of the perturbation. The effectness of two methods is validated by simulation, and simulation results show that the presented algorithm can be used both individually and associatively. By using these methods, the perturbation of vane angle on dynamic process can be reduced, and accordingly, the stability influence of engine in transition process is ensured better.
