Mainly, stepper motors are employed in an open-loop control system, where a lot of shortcomings appear, for example, block or leakage of position by overload, torque reduction by driving in operating range, great power dissipation, and lack of robustness by dynamic loads. Stepper motors are increasingly used in motion control because of their low price and the ability to position well a connected electromechanical system. This driver accomplishes a firm and accurate control and is responsive. The experimental results verified using hardware-in-loop Matlab and Xilinx cosimulation method. The performance of the driver is tested by measuring the distance traveled on linear motion system. In addition, a linear motion system developed (with 4 mm movement per motor revolution) and coupled it to the stepper motor. The driver’s control behavior can be adapted just by altering Verilog scripts. Implementation of driver realized by an FPGA and using Verilog hardware description language in the Xilinx ISE environment. Proposed driver built on a Spartan3 FPGA (XC3S400 core) development board from Xilinx. This paper presents an FPGA-based microstepping driver which drives a linear motion system with a smooth and precise way.
