Abstract
The paper proposes a new method of identifying the linear model of a DC
motor. The parameter estimation is based on the closed-loop step response of
the DC motor under a proportional controller. For the application of the
method, a deliberate delay of the measured speed was introduced. The paper
considers the speed regulation of the direct current motor with negligible
inductance by applying 1-DOF and 2-DOF, proportional integral retarded
controllers. The proportional and integral gain of the PI retarded
controllers was received by using a pole placement method on the identified
model. The Lambert W function was applied for the identification and in
designing the controller with the purpose of finding the rightmost poles of
the closed-loop as well as the boundary conditions for selecting the gain of
the PI controller. The robustness of the calculated controllers was
considered under the effect of an disturbance, uncertainty in each of the DC
motor parameters as well as perturbations in time delay.
