Friction has characteristics that are difficult to equate and for this reason it becomes very important and necessary to identify nonlinearities and subsequently compensate them. In this paper, based on the DC motor equation using Newton’s law of motion, feasible models are presented and friction is measured and analyzed through Matlab and a Quanser data acquisition card. Nonlinear dynamic friction torque is used and compared with the experimental results of a real servomotor.81-94engMathematical modelingNonlinear control systemsNonlinear friction modelCapítulo de livro10.1007/978-3-030-60694-7_52-s2.0-85102190008
