H-bridge driver based motor speed control and implementation

In this study; forward and backward speed control of the permanent magnet direct current (PMDC) motor has been realized by using the pulse width modulation (PWM) method both in the simulation program environment and the implementation. The H-bridge circuit is used to move the motor forward and backward with only one direct current (DA) source. The proportional, integral (PI) control and Sliding Mode Control methods are used separately to follow the desired speed in the designed system. Simulation studies were done using MATLAB / Simulink blocks and Xilinx System Generator (XSG) blocks. The application was implemented by using a DC motor and a Field Programmable Gate Array (FPGA). The results of both simulation studies and experimental study were compared by PI control method and sliding mode control methods. The results of the application were consistent with the results of the simulation study.
