Sensorless direct torque and stator flux control of induction machines using an extended Kalman filter

Sensorless Vector Control of Induction Motor Drive - A Model Based Approach

“…Rotor speed has been considered as a constant by many researchers in speed estimation problem (Schauder, 1992;Tajima & Hori, 1993;Peng & Fukao, 1994;Kim et al, 1994;Comnac et al, 2001;Ma & Gui, 2002;Du et al, 1995;Minami et al, 1991;Veleyez-Reyes & Verghese., 1992;Veleyez-Reyes et al, 1989). The idea is that the speed changes slowly compared to electrical variables.…”

“…In (Schauder, 1992;Tajima & Hori, 1993;Peng & Fukao, 1994) speed was estimated using model reference adaptive system considering it as an unknown constant parameter. In (Kim et al, 1994;Comnac et al, 2001;Ma & Gui, 2002;Du et al, 1995) the speed was considered as an unknown constant state of the machine and extended kalman filter (EKF) was used to estimate it. Recursive least square estimation method was used in (Minami et al, 1991;Veleyez-Reyes & Verghese, 1992;Veleyez-Reyes et al, 1989) for speed estimation considering speed as an unknown constant parameter and found out the value of estimated speed that best fits the measured and calculated data in the dynamic equations of the motor.…”

“…Speed sensorless control technique first appeared in (Abbondante & Brennen, 1975). The commonly used methods for speed estimation are Model Reference Adaptive System (MRAS) (Schauder, 1992;Tajima & Hori, 1993;Peng & Fukao, 1994;Choy et al, 1996), Neural Networks (Simoes & Bose, 1995;Fodor et al, 1995;Ben-Brahim & Kudor, 1995;Kim et al, 2001;Toqeer & Bayindir, 2003;Haghgoeian et al, 2005), Extended Kalman Filter (EKF) (Kim et al,1994, Comnac et al, 2001Ma & Gui, 2002;Du et al, 1995;Thongam & Thoudam, 2004) and Nonlinear Observer (Bodson et al, 1995;Liu et al, 2001, Pappano et al, 1998. The aim of this chapter is to provide with a brief overview of high performance sensorless induction motor drive.…”

“…Several review and comparison papers are available on sensorless control techniques [4][5][6][7]. The commonly used methods for speed estimation are Model Reference Adaptive System (MRAS) [8][9][10][11], Neural Networks [12][13][14][15][16][17][18][19], Extended Kalman Filter (EKF) [20][21][22][23][24][25] and Nonlinear Observer [26][27][28][29]. Techniques for high performance induction motor control implementation requin; precise knowledge of machine parameters, and the rotor resistance being the most important of them.…”

“…In [8][9][10] speed was estimated using MRAS considering it as an unknown constant parameter. In [20][21][22][23] the speed was considered as an unknown constant state of the machine and EKF was used to estimate it. Recursive Least Square Estimation method was used in [59][60][61] for speed estimation considering speed as an unknown constant parameter and found out the value of estimated speed that best fits the measured and calculated data to the dynamic equations of the motor.…”
