• In this work, a nonlinear adaptive control strategy based on deadzone compensation is proposed for Hammerstein nonlinear systems containing input deadzone. The proposed controller is consisted of a recursive estimator and a deadzone compensating control law. By modeling the input deadzone as a combination of a symmetric deadzone and a disturbance term, the parameterization model is introduced. Then the recursive estimator is presented to update the model parameters. Based on the modified certainty equivalence principle, the deadzone compensating control law is derived. The simulation results in a wind tunnel simulation platform are presented. All the signals are bounded in the closed-loop system, and the comparison has verified the merits of the proposed controller.
