This paperpresents a parameter estimation for a permanent magnetic DC motor using the simulink design optimization method.The parameter estimation may be represented as an optimization problem. Firstly, the initial values of the DC motorparameters are extracted using the dynamic model through measuring the values of voltage, current, and speed ofthe motor. Then, these values are used as an initial value for simulink design optimization. The experimentally inputoutputdata can be collected using a suggested microcontroller based circuit that will be used later for estimating theDC motor parameters by building a simulink model. Two optimization algorithms are used, the pattern search andthe nonlinear least square. The results show that the nonlinear least square algorithm gives a more accurate resultthat almost approaches to the actual measured speed response of the motor.
