Abstract:

For the shift actuator control during AMT engagement, an adaptive intelligent control strategy was proposed. The goal is to make the synchronizer displacement follow the target displacement trajectory closely by dual closed-loop control (shift motor current and synchronizer displacement). Considering the shift actuator parameter uncertainty and dynamic disturbance, a compensator control was added to get access to the actual shift motor feature. The compensator gains were obtained by the self-learning algorithm in neuron network, and the input of the self-learning algorithm is the error between shift motor actual current and predicted current by neuron network. Meanwhile, fuzzy adaptive control was utilized to regulate the parameters of PI control in the closed-loop of synchronizer displacement. The target synchronizer displacement trajectory was updated in time by offline and online self-learning strategy. The simulation results verify that compared to normal PID control, the proposed strategy has higher accuracy, better stability and faster response in following target trajectory.

Key words: vehicle engineering, shift actuator, trajectory tracking, self-adaptive, drivability, neuron network, fuzzy algorithm
