Abstract

The used of DC motor these recent years has been increased due to the human needs that been applied to the robotic, machine and others. In this project, the classical technique control which is PI controller has been studied for servo application to drive the system or loads to control speed and torque. The objectives of this project are to obtain good performances of the DC drive which are minimum of overshoot and less sensitive to the parameters variations. Also, this controller has a good dynamic response such as to provide fast transient response and has a minimum overshoot. To design this controller, the cascade control structure has been applied. In this thesis, the torque and speed control is been discussed. In the first stage, the PI controller is designed to get the proper value of PI controllers with Linear Theory Analysis. Then the PI values of the torque and speed will be evaluated under a large signal analysis. The implementation of hardware for torque control, there are several main components that had been used such as, Integrated circuit (IC) analogue, comparator, triangular waveform generator, current transducer, gate drivers, DC-DC converter and others. The hardware of torque control of DC motor has been tested to ensure the practical experimental results, satisfied with the simulation results.
