Fuzzy PI control of maglev guiding system based on feedback linearization

This paper describes the design of feedback linearization and fuzzy PI controllers for the maglev guiding system of linear elevator. The controllers so designed based on the nonlinear control techniques are applied to control the gap of permanent magnet synchronous linear motor (PMLSM) with the aim of improving the vertical thrust and control the horizontal vibration and noise in the process of elevator operation. Matlab modeling of this system is used in this paper. The simulation result of the entire system are presented in this paper.
