Dual-Adaptive Clutch Control of Tractor Clutch Considering Real-Time Compensation of Temperature and Wear

In this paper, a triple-clutch power shift transmission is proposed as a means of enhancing the performance of a dual-clutch transmission in a tractor. However, it should be noted that the oil temperature and the wear of the clutch have a detrimental effect on the performance of the proposed transmission. Consequently, an adaptive control strategy is proposed for the clutch in terms of oil temperature and wear. In order to address the issue of the timeliness of temperature compensation, an adaptive fuzzy control strategy is proposed with a view to improving the control of the peak oil filling pressure, pre-filling time, and bonding time. This paper sets out a proposed adaptive iterative control strategy for the compensation of wear, with a view to regulating the pressure at different stages of the filling process. The two proposed control strategies are then subjected to rigorous testing in a test bench to ascertain their effectiveness. The findings indicate that the proposed strategy is capable of effectively mitigating the deviation of clutch binding resulting from fluctuations in oil temperature and wear, thereby enhancing the performance of agricultural machinery transmissions.
