摘　　要：针对农用汽车电动助力转向系统非线性较强、稳定性较差等问题,基于模糊ARTMAP神经网络,建立农用汽车电动助力转向系统控制模型,对电动助力转向系统中的驱动力矩和助力力矩进行控制,利用matlab仿真软件进行分析。分析结果表明,随着驱动力矩的增加,助力力矩逐渐增加,但是增加的趋势先增加后减小;驱动和助力力矩的目标值与仿真值在仿真初期存在一定的差异,随着时间的增加,两者差异逐渐减小直至为零;设计的基于模糊ARTMAP神经网络的控制系统,控制精度较高,稳定性较好,可以满足要求。For the problems of nonlinear, the poor stability of electric power steering system of agricultural vehicle, the control model of the electric power steering system of agricultural vehicle was established based on the fuzzy ARTMAP neural network to control the torque of driving torque and power steering torque, the analysis was used by matlab simulation software. The analysis results show that with the increase of the driving torque, power steering torque increase gradually, but the increase trend of first increases then decreases; the target value and simulation value of driving torque and power steering torque at the beginning has certain differences, with the increase of time, both difference decreases to zero; design of control system based on fuzzy ARTMAP neural network of high control precision, good stability can meet the requirements.
