Speed control of a DC motor is one of the main engineering applications. The full

wave rectifier could be used to control the speed of a DC Motor by changing the input

voltage demanded. Moreover, a PID controller is carried out to provide a robust

system response. Figure 3 shows the block diagram for the system including the PID

controller. Investigate the followings using the MATLAB/Simulink software:
