Electromagnetic Suspension System for Control of Limb Volume in Prosthetics

Evaluation of new suspension system for limb prosthetics

BACKGROUND Good prosthetic suspension system secures the residual limb inside the prosthetic socket and enables easy donning and doffing. This study aimed to introduce, evaluate and compare a newly designed prosthetic suspension system (HOLO) with the current suspension systems (suction, pin/lock and magnetic systems). METHODS All the suspension systems were tested (tensile testing machine) i...

Optimal Control of Electromagnetic Suspension EMS System

This paper presents the controller design of magnetic levitation application. The highly nonlinear electromagnetic suspension EMS system is hard and limited system control subjected to prescribed stability of system. Due to the nonlinear dynamics of system, the linearization of the nonlinear EMS plant is described by linear model. An attraction force about the prescribed nominal operating point...

Control of an automotive electromagnetic suspension system

The main research goal of this thesis is to determine what performance gains can be achieved with a high bandwidth electromagnetic active suspension. As a baseline vehicle a BMW 530i is used, for which a retrofit electromagnetic suspension consisting of a spring and tubular permanent magnet actuator (TPMA) is designed. To design a control system for this actuator, a model of the BMW has been cr...
