Abstract

In order to improve the tracking and robust performances of a linear elevator driving by permanent magnet linear synchronous motor (PMLSM), a stable adaptive fuzzy sliding mode controller (AFSMC) for a linear motor speed loop control is presented, The fuzzy system is applied to approximate the unknown nonlinear function of plant, and then the estimation value of nonlinear function is used to design the control variable. Analysis of simulations reveals that proposed method is robust in the presence of uncertainties and bounded external disturbances.
