Abstract :
At different working condition, the turbofan engine presents nonlinear characteristic. The turbofan engine is described as a nonlinear model with bounded perturbations at a certain working point and a robust turbofan engine fan speed control method based on signal compensation is proposed. A controller designed by this method consists of a nominal controller and a robust compensator. The controller has a simple structure and a single adjusting parameter. Robust control property of the closed-loop system is proven. The simulation based on the CMAPSS database verifies the robust compensation with varying input condition.
