Article: Variable frequency speed control method for wheeled grain harvester based on fuzzy control theory Journal: International Journal of Modelling, Identification and Control (IJMIC) 2025 Vol.46 No.2 pp.82 - 90 Abstract: With the advancement of agricultural mechanisation, higher requirements have been proposed for the work efficiency, automation level, and energy-saving performance of grain harvesters. Aiming to reduce the coefficient of variation of data and speed control overshoot, this paper designs a variable frequency speed control method for wheel grain harvesters based on fuzzy control theory. A frequency conversion mathematical model for wheeled grain harvesters was constructed, with motor speed online estimation achieved through adaptive disturbance rejection design and adaptive estimation model. Finally, fuzzy rules, feedforward compensation, and PID controller optimisation were utilised to enable dynamic parameter adjustment and precise speed control. Experimental results demonstrated that after applying this method, the speed data coefficient of variation decreased from 0.06 to 0.02, with maximum speed overshoot reaching only 2.97%.

Abstract: With the advancement of agricultural mechanisation, higher requirements have been proposed for the work efficiency, automation level, and energy-saving performance of grain harvesters. Aiming to reduce the coefficient of variation of data and speed control overshoot, this paper designs a variable frequency speed control method for wheel grain harvesters based on fuzzy control theory. A frequency conversion mathematical model for wheeled grain harvesters was constructed, with motor speed online estimation achieved through adaptive disturbance rejection design and adaptive estimation model. Finally, fuzzy rules, feedforward compensation, and PID controller optimisation were utilised to enable dynamic parameter adjustment and precise speed control. Experimental results demonstrated that after applying this method, the speed data coefficient of variation decreased from 0.06 to 0.02, with maximum speed overshoot reaching only 2.97%.
