In this paper, a novel active vibration control method for house structure by using magnetic levitation (MAGLEV) is proposed. Instead of active mass damper (AMD), a MAGLEV device is developed to provide the force for reducing the vibration from the wind or transportation. When a vibration occurs, the developed MAGLEV device will repeat to levitate and contact to the ceiling of housing properly. According...
The goal of this paper is utilization of the state observer to research a new capability of controlling the axial gap self-bearing motor. Analytical and experimental evaluation for a sensorless speed vector control of a salient axial gap self-bearing motor is presented. The approach is based on the estimation of the extended electromotive force (EEMF) through a Luenberger Observer (LO) with help of...
This paper presents an improvement of sensorless speed vector control for a nonsalient type axial gap self bearing motor (AGBM), in which rotor speed and position are estimated by using sliding mode observer with full mathematical model. The approach is based on the estimation of the motor back-EMF (or induced voltage) through a sliding mode observer with help of reference voltages, measured stator...
