On the design of magnetic suspension systems

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

First, the dynamic performance of magnetic suspension systems (Figures 1-3), which are designed on the basis of linear feedback laws, are examined. Then, nonlinear control laws are developed to make the dynamics of a suspension system to be exactly that of a linear spring-mass-damper system. It is found that such control laws are not defined for all initial conditions of the supported mass. Lastly, it is shown that it is possible to achieve a true spring-mass-damper behavior for all initial conditions by using two electromagnets, but operating only one at a time.
