This paper describes the design of an electromagnetic elevator guiding system. One challenge of this design is the overdetermination of the mechanical system due to its high number of adjustment variables. Force decoupling, transformation from local to global quantities, and simulation results of the entire system are presented. In contrast to former works, a new elevator test bench for the evaluation...
To improve the resolution of the very large telescope interferometer (VLTI) a two-stage mechanical system, a so called differential delay line (DDL), is developed jointly by the EPFL and the Observatory of Geneva. The system is designed to reach nanometer accuracy at high bandwidth over large displacements. The coarse stage features a permanent magnet (PM) stepper motor driving a lead screw connected...
The design of advanced mechatronic systems involves the integrated design of the mechanical system, of the actuator assuring the precise movements inside the system and of its control unit. In order to make proper choices early in the design stage, innovative tools are required to model and simulate both the entire physical system and each subsystem which are composing the mechatronic device. The...
