“…Figure 8 illustrates the general configuration of the full-order observer in which G stands for the observer gain matrix with 4 × 2 size, which implies the difficulty of this design. This design problem originates from (35), and much attention has been paid and many observer gain design strategies and formulations have been derived (10) (36)- (40) .…”

This paper surveys some notable efforts on improvement of position sensorless control of interior permanent magnet synchronous motors and synchronous reluctance motors. These motors are widely utilized for saving energy and for their high power density, and the control techniques for these motors have advanced to address recent trends in motor development. This paper focuses particularly on the position estimation and current control techniques developed in Japan for motors with considerable magnetic non-linearity and demonstrates solutions that have been proposed for improvements in the performance of position sensorless control.

“…ROTOR-POSITION OBSERVER To avoid forbiddingly complicated equations, which would prevent analytical results from being derived, accurate parameter estimates L d , L q , and ψ pm are assumed 1 , with the exception of the stator-resistance estimateR s . Without loss of generality, the observer in estimated rotor coordinates is considered.…”

Abstract-A reduced-order position observer with statorresistance adaptation is proposed for motion-sensorless permanent-magnet synchronous motor drives. A general analytical solution for the stabilizing observer gain and stability conditions for the stator-resistance adaptation are derived. Under these conditions, the local stability of the position and stator-resistance estimation is guaranteed at every operating point except the zero frequency, if other motor parameters are known. The proposed observer design is experimentally tested using a 2.2-kW motor drive; stable operation at very low speeds under different loading conditions is demonstrated.

“…An error term is calculated from the measured and estimated quantities, and the rotor speed is usually adjusted by a PI mechanism. The current or the stator flux has been used as a state variable of the observer [3]- [8]. An observer design using the stator flux error as a state variable has also been proposed [9].…”

Abstract-This paper deals with a speed and position estimation method for the sensorless control of permanent magnet synchronous motors. The method is based on a speed-adaptive observer. The dynamics of the system are analyzed by linearizing both the motor model and the observer, and the observer gain is selected to give improved damping and noise suppression. At low speeds, the observer is augmented with a signal injection technique, providing stable operation down to zero speed. The experimental results, obtained using a 2.2-kW interior magnet motor, are in agreement with the results of the analysis.
