The theory of motion control has evolved since the late 18th century. Simply, motion control is defined as accurately controlling the movement of an object based on speed, distance, load, inertia or a combination of all these factors. Due to high system complexity and difficult software language implementation, the traditional programmable logic controller based motion control systems have gradually been replaced by CPLD based control systems. In my project, the control to a stepper motor system is accomplished from a mobile and an intuitive and easy to use graphical user interface is designed by using VHDL. My paper presents, a hardware implementation of circuit which is designed for a programmable rotational stepper motor using VHDL as a design tool and the CPLD as a target technology. The design is implemented on a XC9572 kit. The advantage of using reconfigurable hardware (CPLD) instead of a PLC, Microprocessor & Microcontroller is that the designer can make modifications to the design easily and quickly, and the total design represents an embedded system. The total programmable hardware design that make control on the stepper motor movement, occupy an area that did not exceed 12% of the chip resources.
