PARAMETER IDENTIFICATION AND MODELLING OF SEPARATELY EXCITED DC MOTOR
Keywords:
DC Motor;, ransfer function;, Simulink., PIDAbstract
DC Motors can be used in various applications and can be used in various sizes and rates as per the applications. In this paper we have focused on the physical parameters of DC motor. Modelling of any system is an important task in control applications because the electrical and mechanical components should be represented in mathematical form. Physical parameters are important in calculating the transfer function of DC motor. By using the physical parameters one can design the controller for controlling speed of the motor. A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. The controller attempts to minimize the error by adjusting the process control inputs. The weighted sum of the proportionate, integrate, differentiate actions is used to adjust the process via a control element such as the position of a control valve, or the power supplied.
