Deadzone compensation in motion control systems using model reference direct inverse control

This work introduces the application of the model reference direct inverse control technique for compensating the deadzone of DC servo systems. In order to improve the control performance related to modeling errors and disturbances, we design a proportional integral fuzzy controller in the feedback loop. Though the implementation of the proposed control is simple, results demonstrate a better behavior than more complex control techniques proposed in the literature. We study the robustness of the proposed system varying different parameters of the system.
