Abstract: The key of stable suspension of bearingless permanent magnet synchronous motor is the closed-loopcontrol of rotor radial position displacement. Usually，the high performance suspension operation of the motor relies on displacement sensor，which destroys the robustness of the motor structure and hinders the lo...

Abstract: For interior permanent magnet synchronous motor(IPMSM) , accuracy of its discrete-time model isusually at the cost of complexity. To find out a way out of the dilemma, stator flux is chosen as the state variable,allowing its model be represented in the complex form and resulting in a concise model in appear...
