Self-tuning control design strategy for an electronic throttle with experimental robustness analysis

In this paper a self-tuning control design strategy for the electronic throttle is introduced. The proposed control design consists of a modified PID controller and an additional nonlinear controller that helps to compensate the nonlinearities of the plant. The control parameters are calculated automatically using an appropriate process identification algorithm. The efficiency of the proposed control design strategy is shown by experimental results. In a next step the performance loss due to aging effects is analyzed. Finally, the robustness properties with regards to environmental influences are investigated.
