| Abstract: | The dynamic stability of a feedback controlled electromagnetic levitation (EML) body is studied. From the theory of dynamic stability,the stability conditions of the controlled EML mody moving in vertical direction are found.After that,the control parameters of the system can be selected such that the body is stablly controlled into the desirable state in vertical position when the body deviates owing to an external disturbance of displacement or velocity.Finally,some examples for numerical simulations are presented. |
