PERMANENT MAGNET DC MOTOR ANALYSIS USING MATLAB: A Comparative Analysis
A Comparative Analysis of PMDC with variation in its parameters The responses here obtained are very limited in their expressions in the sense that they do not provide the comparative results between the responses if any parameter is changed. For the accomplishment of the fore mentioned task separate .m files were created each varying one parameter i.e. Resistance, R; Inductance, L; Inertia of the load and the motor system, J and the damping of the load and the motor system, B. The results are based on the fact that each of the above mentioned parameters are changed one by one and the response of the motor and the behavior of the natural frequency and the damping ratio of the whole system are plotted are against them. Variation in: Resistance, R Important Observations: Step Response of the system As the resistance of the system is in creased the overall response of the system to the step input that is the output angular velocity of the system decreas
