A State Observer For The Permanent-Magnet Synchronous Motor [PDF]
SPIE Proceedings, 1987 An identity state observer for the permanent-magnet synchronous motor is derived which reconstructs the electrical and mechanical states of the motor from current and voltage measurements. The observer operates in the rotor frame and estimates direct and quadrature stator currents, rotor velocity, and rotor position.
