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...

Open Loop Analysis of the PMDC Motor

Hello friends !!! i am here to share my project work with you.   i have done a comparative analysis of PMDC motor  to  show the variation in response by changing its parameters.. the introduction of PMDC motors can be view by checking the page linked on this page. we'll start with open loop analysis of the motor. Open Loop Analysis of the PM DC Motor The open loop analysis is done using MATLAB ® . Open loop analysis using MATLAB ® .m-file With the aid of the PM DC motor parameters provided, the open loop analysis us done by considering the stability factors and making the necessary plots for this analysis. This includes the step response and the bode plot diagram. For this purpose, separate m files were created for the constants, file to change these constants and the main files. constants.m % start of code % motor parameters L = 0.12 R = 7 Kt = .0141 J = 1.6e-6 Ke = .0141 B = 6.04e-6 % end of code The above file generated constants.m sto...
