title = "Cascaded observers for the rotor position, speed and load torque of the PMSM using an extended dynamic model",
abstract = "The paper presents a method for the estimation of the EMFs, speed, rotor position and load torque of the permanent magnet synchronous motor (PMSM) which are typically needed in sensorless control. The estimation approach uses an extended dynamic model of the motor and is done with cascaded observers; one of them employs an adaptive law. A first observer estimates the EMFs of the motor -they are fed in the tan-1 function to compute the angle of rotor position. The EMFs and the rotor position are fed into a second observer - this estimates the speed of the PMSM as well as the load torque. The load torque is obtained based on an adaptive law. In the paper, the mathematics of the observers and subsequent simulations are shown.",
