Abstract: An adaptive inverse controller based on filtered-ε LMS algorithm for the complex aeroengines is designed. The model and the inverse model of the aeroengine are designed by using nonlinear-filters. The weights of the controller are adjusted on-line until the system error trend to zero. Simulation of the speed control for aeroengine in full flight envelope is presented to verify the method. The control structure does not rely on the exact model. The control system has satisfactory tracing performance and good robustness.
