Research on Position Tracking Control of Electro-Pneumatic AMT Clutch

摘要

A new control strategy is proposed in this paper to realize precise position tracking control of electro-pneumatic AMT clutch. The control strategy is designed according to the analysis of clutch system structure and characteristics. The control system consists of two parts, including logic-switched controller and improved single neuron PID controller. The logic controller decides which valves to work according to position error, and the single neuron PID controller generates PWM signals to the working valves. The controller achieves strong robustness and adaptability through self-learning and adjustment on the weight and the gain. The controller just depends on the position error to calculate control signals, and it has a simple structure to design and implement easily. By making comparative experiments with classical PID controller, the tracking results for step response and changing linear position show that the controller designed can achieve better stability and robustness.
