车载仪表用电机驱动控制系统的研究

针对汽车仪表上面指针需平稳地转到目标位置、精确地反映车况信息,基于汽车仪表用步进电机6405 R475,提出一套驱动控制系统.介绍了该汽车仪表用步进电机的分步、微步驱动原理,并搭建微步驱动模型.然后具体分析了该汽车仪表用电机不归0对后续控制的影响,并对归0的过程进行了设计.最后对抛物线形S曲线的数学模型进行了分析,并基于该S曲线对该汽车仪表电机在转动过程中进行算法规划.通过实验证明,该套控制系统能够满足设计需求.

Research in drive control system of vehicle stepper motor

According to that indicator should move to target location precisely and smoothly,a drive control system is put forward based on vehicle stepper motor 6405 R475.Substep driving principle and microstep driving principle of the vehicle stepper motor are introduced,and a microstep driving model is designed.And then no return to zero of the vehicle stepper motor impact on the follow-up control is analyzed,and the process of return zero has carried on the design.Finally,the parabolic S curve mathematical model is analyzed,and the algorithm plan based on the parabolic S curve is built for the vehicle stepper motor's acceleration and deceleration control.Experimental results show that this system of control can meet need for design.
