Modeling of DC Motor and Choosing the Best Gains for PID Controller

NAMIKI 12 volt DC motor is used to model mathematically. L298 N hybrid motor driver is used to drive the motor. Voltage for the motor to drive to the desired angle is applied from the PWM of the motor. The best PWM value for the motor is considered by using PID controller from the Arduino processor. The actual angle of the motor is get from the optical encoders. The best gain for PID controller is get from Ziegler Nichols method and Simulink of MATHLAB software by using mathematical modelling equation of the motor. The modelling equation is get from two kinds of calculation. The first approach is from parameters estimation of the motor. The second is from first order differential equation. Then, the best PWM value is get for the position control of the motor. This motor is used for the robot arm.
