Abstract: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 followup 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.
