The investigated linear machine works as a mechanical oscillator using springs to reduce the overall power consumption and two electromagnets having their twin circular coils (which surround a ring-shape permanent magnet) connected in series. The actuator can be controlled with a single phase inverter. In this paper sensorless closed loop position control based on a FEM assisted estimator that uses...
Three models of a hybrid magnetic suspension system are separately built under the condition of no time-delay, time-delay of the signal of suspension gap and time-delay of arithmetic. To research on the influence of time-delay on the performance of the hybrid magnetic suspension system, relationship between the latent roots of the closed-loop system and time-delay, and the relationship between the...
