An observer for speed sensorless induction motor drive
Proceedings of 1994 IEEE International Symposium on Industrial Electronics (ISIE'94), 2002An observer for a speed sensorless induction motor drive is proposed in the paper. It is easy to implement on a microprocessor with particular reference to high performance drives requiring the vectorial control technique which needs a flux observer. The proposed speed observer is based on an adequate arrangement of the error system equations, written ...

A flux and speed observer for sensorless SPIM applications
The XIX International Conference on Electrical Machines - ICEM 2010, 2010It is usual to find single-phase induction motor (SPIM) in several house, office, shopping, farm, and industry appliances, which is become more sophisticated and requires the development of high performance alternatives to drive a SPIM. All proposed strategies to improve the performance SPIM need the evaluation of the rotational speed or position ...

Sensorless control of AC motors at zero speed
ISIE '99. Proceedings of the IEEE International Symposium on Industrial Electronics (Cat. No.99TH8465), 2003The paper presents a review of the main approaches to sensorless control of AC motor drives, pointing out the problems related to zero speed operations. A general sensorless vector control technique able to drive different kinds of AC motors at low and zero speed is then presented. The proposed control scheme exploits the anisotropy of the machines and

A speed observer for speed sensorless control of induction motor
2010 2nd International Conference on Future Computer and Communication, 2010This paper proposes a novel speed sensorless control strategy for induction motor drives based on active-disturbance rejection controller. Based on the field-oriented control technique, the dynamic model of q-axis current is a first order nonlinear state equation including synchronous speed and rotor speed.

Sensorless Speed Control of PMSM Motor for Wide Speed Range
2021 1st International Conference on Power Electronics and Energy (ICPEE), 2021This paper compares the sensorless vector control techniques of Permanent Magnet Synchronous Motors (PMSM). Sliding mode observer (SMO) and Model reference adaptive system (MRAS) are compared. SMO are known for their robust nature. The SMO is traditionally used for sensorless control.

Sensorless vector and speed control of brushless motor drives
IEEE Transactions on Industrial Electronics, 1994In the present paper an approach is presented to the speed control of permanent magnet synchronous motors without mechanical transducers. The rotor position, which is an essential component of any vector control scheme, is calculated through the instantaneous stator flux position and an estimated value of the load angle. A closed-loop state observer is

An adaptive speed sensorless observer for induction motor drives
IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002An adaptive speed sensorless fourth order observer for online estimating rotor flux and speed in induction motor drives is presented in the paper. The synthesis procedure of the adaptive observer is based on the hyper-stability theory. Assuming the speed as unknown parameter of the rotor flux observer, the online identification process of its value has

Speed-Sensorless Predictive Direct Speed Control for PMSM Drives
2023 IEEE 8th Southern Power Electronics Conference and 17th Brazilian Power Electronics Conference (SPEC/COBEP), 2023Predictive direct speed control (PDSC) of electric motors makes the control of both electrical and mechanical systems possible over a single control law by eliminating the cascade control structure. Speed-sensorless control also reduces the cost of electric drive while increasing system reliability.

Robust speed identification for speed-sensorless vector control of induction motors
IEEE Transactions on Industry Applications, 1994This paper describes a new approach to estimating induction motor speed from measured terminal voltages and currents for speed-sensorless vector control. The proposed approach is based on observing the instantaneous reactive power of the motor. The estimated speed is used as feedback in an indirect vector control system. The described technique is very

Adaptive observers for speed sensorless IMs
International Journal of Systems, Control and Communications, 2015In this paper, one proposes an approach which allows the design adaptive observers for a class of uniformly observable nonlinear MIMO systems with linear parameterisations. The structure of the proposed observer is simple and it is able to give rise to different observers: 1 adaptive high gain observer for linearly parameterised; 2 adaptive sliding ...
