Abstract: In this paper, adaptive inverse control is developed to deal with the problem about the control performance of non-linear systems, which are affected by the uncertainty of the parameters and external disturbance. An adaptive inverse controller, which is used as a feed forward controller, is designed to realise real-time tracking of the system output and to enhance the robustness of the system under parameter perturbation. A noise and disturbance canceller is used to eliminate the influence of external disturbance and measurement noise for open loop system output. The results of a simulation conducted on the variable frequency speed control system of an induction motor verify the feasibility and effectiveness of the proposed method.
