Abstract:
Mathematical models and their parameters are essential when designing controllers because they allow the
designer to predict the closed loop behavior of the system. An accurate method for estimating the DC Motor-Gear-Alternator
(MGA) system parameters is needed before constructing the reliable model. This paper proposed a new method of parameter
estimation using Matlab/Simulink parameter estimation tool via Step Response Methodology. Optimization algorithms
including the nonlinear least square, Gradient Descent, Simplex Search and Pattern Search are discussed. Simulink Design
Optimization automatically estimated parameters of the MGA model from measured input-output data.
