Abstract: This study concerns a robust control algorithm of an innovated structure of linear switching synchronous motor dedicated to monitoring of automated elevators. This control algorithm is based on the pulse width modulation technique imposing currents sum of a continuous value and a value having a shape varying in phase opposition with the variation of the inductances. This control technology can greatly reduce vibration of the entire system due to the strong fluctuation of the torque developed by the actuator, generally characterizing switching synchronous motors. A modelling program taking in account of system interactions is developed. This program is validated following the implementation and the simulation of the control model in the simulation environment Matlab-Simulink. Simulation results are with good scientific level and encourage subsequently the industrialization of the global system.
