“…Some work has also been reported on sensorless control of brush-less DC [10], stepper motors [5,15,29] and permanent magnet synchronous motors (PMSMs) [25]. 1 In this paper we are interested in sensorless control of, and more particularly on observer design for, PMSMs.…”

The control algorithms used in high performance AC drives require the knowledge of rotor position and, in the case of speed regulation, also of speed. Since in many applications rotational transducers cannot be installed, their reconstruction is needed. The use of observers is stymied by the fact that the dynamics of electrical machines are highly nonlinear and does not belong to the class studied by the nonlinear control community. In this paper solutions to both problems, which are particularly tailored for the widely popular permanent magnet synchronous motors, 1 are provided. A key step for the design of both observers is the choice of a suitable set of coordinates. The position observer is a standard gradient search whose detailed analysis reveals outstanding (global asymptotic) stability properties. Furthermore, the analysis clearly exhibits the interplay between rotor speed and the gain of the gradient search-that (essentially) determines its convergence rate. The position observer is a simple two-dimensional nonlinear system, hence is easily implementable. The speed observer is designed following the immersion and invariance technique and is also shown to be globally convergent. Simulation and experimental results of the position observer, used together with a classical field-oriented control algorithm, are presented.

“…During the past several decades, extensive speed sensorless approaches have been reported and widely performed in many industrial applications, which can be grouped as [127,128]: fundamental model with measured currents and voltages based algebraic operation methods [129][130][131], back-EMF sensing based methods [132][133][134], and mathematical model based speed estimators [135][136][137][138][139][140][141].…”

This paper deals with the latest developments in Permanent Magnet Brushless DC (PMBLDC) motor drives. A comprehensive account of the stateof-the-art on types of construction of the motor, closed loop controllers in position, speed and current/torque control and recent trends in inverters, sensors etc. are given. Techniques for mechanical sensors elimination are discussed in detail. Special efforts made to reduce torque ripples, noise and vibrations are described. The impact of microelectronics through integrated chips used in the control of PMBLDC motor drives is given. The increasing applications of this drive due to improved performance and its cost reduction are also enlisted.
