Abstract:

Direct Current (DC) motors have been extensively used in many industrial applications. Therefore, the control of the speed of a DC motor is an important issue and has been studied since the early decades in the last century. Proportional-Integrated-Derivative (PID) controller is one of the methods to control synchronize multiple motor. But the settling time is slow for this controller and its affect the performance too. This paper presents Linear Quadratic Regulator (LQR) controller which is another method of control synchronize multiple motor to reduce the settling time of the multiple motor using MATLAB software. The settling time result of the LQR controller is compared with PID controller.
