The most industrial applications use the variation of the torque, speed and/or position in process, for which extremely severe specifications are needed. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. One thus tries to make fulfill the speed measurement by implementing in a Digital signal processor (DSP) an algorithm of speed estimation using the current and voltage acquisition. Those methods become realizable on DSP of low costs. The goal of this work is to design, develop and implement of sensorless speed digital control of an electric motorization. The position and the mechanical speed of motor are calculated according to: observed rotor flux and the slip pulsation. The algorithm is implemented in DSPic30f of Microchip.


Experimental investigation of shaft transducerless speed and position control of ac induction and interior permanent magnet motors
Goksu, Omer; Hava, Ahmet Masum (2010-01-01)
In order to drive AC motors with high efficiency and high motion performance, and to provide accurate speed/position control, motor shaft speed and/or position feedback is required. For this purpose, usually transducers (encoder, tachogenerator, resolver, etc.) are installed on the shaft. However, transducers are not preferred in most of the applications since they increase the cost and decrease the reliability of the drive due to their failure prone structure and connections. In such applications, the spee...
Design optimization of variable frequency driven three-phase induction motors
Ertan, B; Leblebicioğlu, Mehmet Kemal; Simsir, B; Hamarat, S; Cekic, A; Pirgaip, M (1998-01-01)
An approach to optimize the design of three-phase induction motors for a wide speed range drive is considered. Two operating points in the speed range are taken into consideration. The problem is handled as a constrained optimization problem. An accurate model for the motor in terms of its dimensions has been developed which predicts the motor performance based on about 60 parameters of motor geometry.
Comparison of Matrix Converter Induction Motor Drive Control Methods
Lettl, Jiri; Kuzmanovic, Dragan; Fligl, Stanislav (2011-09-10)
In this paper, the implementation of the Field Oriented Control and the Direct Torque Control in matrix converter supplied induction motor drives is analysed, and compared with the implementation in drives supplied by the Voltage Source Inverter. The analysis is accompanied by the results of numerical simulations and experimental implementations of these two control methods.
Implementation issues of real time position estimation for induction motors using rotor slot harmonics
Ertan, Hulusi Bülent; Keysan, Ozan (2013-11-15)
In this paper, an approach to identify rotor slot harmonics, from motor currents or from induced voltage in an internal or external search coil voltage is described. The importance of this method is that instantaneous value of the rotor slot harmonics can be determined in real time. In this manner, it is possible to determine motor speed or rotor position of a motor in a short enough time, for use in vector control. This method is independent of motor parameters. Using this method an additional feedback bec...
