Application Research on the Tractor Based on the Automatic Control Technology

In order to further improve the field work efficiency and job performance of the tractor,the hybrid electric drive control system of the tractor was improved by using automatic control technology.Through the thorough understanding of the working principle and characteristics of the tractor,then integrated the disturbance observation mechanism,the dual power flow theory and the closed loop regulation function,three major modules of the tractor were analyzed and optimized one by one,which were the navigation control,the variable speed setting and the intelligent display,then the intelligent test was made,and it was concluded that the tractor navigation system error rate could be reduced by 2.4%and variable speed control sensitivity could be increased from 89.50%to 92.80%,intelligent display accuracy increased by 13.67%,and the vehicle integrated efficiency increased by 22.26%after the optimization,the results showed that the effect of the tractor control improvement was feasible based on automatic control technology,which not only could provide some ideas for other agricultural machinery,but also would be strong practical reference value.
