Abstract

An adaptive friction compensation scheme is presented in this paper to compensate the dynamic friction as well as the inertia variation and load disturbance that exist in the induction motor drives. A third-order linear dynamic model is used for the induction motor drives while the LuGre dynamic friction model with nonuniform friction force variations characterizes the friction force between the contact surfaces. Parametric uncertainties are assumed to capture the variations. Thus, the update laws are designed to estimate the unknown system parameters. The system stability and asymptotic position tracking performance are guaranteed by the Lyapunov function and are shown through the simulation results
