摘要：Transfer function is a widely employed kind of mathematical model. First order and second order transfer function with voltage input and motor speed output are broadly used as models of BLDC motor. Since there exists uncertainty and nonlinear phenomena in the real time world, simulation and practical experiment have been done to compare uncertainty among the first order model, second order model and the real model in this brief. The object of this brief is to find out which model can present the real BLDC motor more accurately and the magnitude of system outcome differences between the theoretical model and the real one, which is a mean of measuring the uncertainty between the theoretical model and the real model. © 2018 IEEE.
