Abstract :To further improve the transient and steady-state performance of automotive electronic throttle position tracking, in this paper an adaptive prescribed performance servo control strategy is designed and applied to a real electronic throttle control system. In view of the possible high gain of the prescribed performance controller in practice, the actuator constraint is also considered in the controller design. The designed servo controller can ensure the transient and steady-state responses of tracking error are limited in the range prescribed by the performance function, and converge with the prescribed convergence rate and have no overshoot. The incorporated adaptive updating law can enhance the robustness of the transient and steady-state performance against uncertainty from the product tolerance, the operating conditions, and the aging of components. Both Matlab/Simulink simulation and dSPACE-based hardware-in-the-loop experimental verification show the effectiveness and applicability of the proposed control strategy.Keywords : Automotive electronic throttle, position tracking, prescribed performance, adaptive technique
