摘要
对无刷直流电机直接驱动履带车辆的转向控制进行了分析研究 ,提出了在双环调速基础上 ,引入自适应修正参数对PWM占空比进行修正的控制方法 ,该方法能够及时补偿由于转向半径的不同 ,内外侧主动轮所受的扭矩大小实时变化对转向所产生的负面影响 ,从而改善了转向性能 .仿真结果表明了该方法的正确性和可行性 .
Turning control on electric track vehicle droved by BLDCM is researched in the paper.On the base of speed-current loops adjustment,the paper puts forward a new digital control method--a adaptability parameter to adjust duty ratio.The function of the method is to compensate the negative effect which caused by disturbance in time and improve turning performs.The simulate results proved that the method is correct and valid.
