Solar tracking system with high precision implementation on FPGA with GUI on LabVIEW

The control techniques for the Stepper motor system in wireless mode using Hardware Description Language (VHDL) for solar tracking system is designed in which due to no mechanical brakes and lower torque (unique torque characteristics). Higher precision of stepper motor is achieved by implementing the techniques and controlled through SPARTAN 3E SRAM based Field Programmable Gate Array (FPGA) controller. The motor is controlled using PWM technique which produces the accurate current pulses to the motor windings to excite. The control parameters are implemented by GUI using LabVIEW platform which is sent through Bluetooth to the controller by which the motor can be controlled in either direction or any angle of rotation. These types of controlling techniques can be implemented in many fields of robot applications. The Simulation design and hardware setup are executed successfully.
