Abstract

In the work, the universal driving joint with the traditional series composite mechanical structure has the friction and wear, which make the moving parts hot, and then causes the static and dynamic performance of the joint worse. So based on the Integration of multi technology domains, such as motors, magnetic levitation and robotics, we present a new magnetic levitation spherical active joint with multi freedom degree. Then the air gap magnetic-energy principle of the electromechanical energy conversion which produces magnetic suspending force and electromagnetic torque is analyzed, and the state synchronous suspension control of rotor based on based on the principle of state reconstruction and self-detection feedback control without sensors are established. The simulation results show that the system has high precision and strong ability of anti-interference.
