英文摘要
      In the light of the high requirements of transient and static performance of automotive electronic throttle systems and the characteristics of nonlinearity and parameter uncertainty, an adaptive fixed-time prescribed performance control strategy is proposed by integrating the prescribed performance control with the fixed-time stability theory and utilizing adaptive online adjustment technique. By defining the improved prescribed performance, the fixed-time convergence, and the real-time adjustment of control parameters, the closed-loop control system possesses the high-performance position tracking to an arbitrary reference signal and the robustness to parameter perturbations and load disturbance. The effectiveness and superiority of the designed controller are verified by both the MATLAB/Simulink simulation and the dSPACE-based hardware-in-the-loop test experiment.
