   SPEED SENSORLESS HIGH PERFORMANCE CONTROL FOR TRACTION DRIVES
By M. Depenbrock; F. Hoffmann; S. Koch [View]
[Download]

Abstract: This paper presents an advantageous way for calculating the speed of an induction machine fed by an IGBT inverter without any mechanical transducers. The good performance of the proposed method, which needs with motor currents and d.c. link voltage only easy measurable quantities for speed estimation, is tested with Indirect Self Control (ISC), a control scheme in a stator-fixed reference frame. By using a complete motor model the difference between the estimated and measured motor currents can be used for calculating the speed and other parameters like stator and rotor resistance.

   A COMPARISON OF MODEL REFERENCE ADAPTIVE SYSTEM AND EXTENDED KALMAN FILTER ESTIMATORS FOR SENSORLESS VECTOR DRIVES
By G. J. Armstrong; D. J. Atkinson [View]
[Download]

Abstract: The performance of Model Reference Adaptive System (MRAS) and Extended Kalman Filter (EKF) estimators for use in vector controlled induction motor drives is evaluated. Each technique is considered in the context of closed loop rotor flux oriented control of the induction machine. The affects of estimator parameter variation on real-time experimental implementation are considered.

   CONTROL OF AN INDUCTION MOTOR WITHOUT SHAFT ENCODER USING THE VECON-CHIP
By 0. Fenker; W. Schumacher [View]
[Download]

Abstract: In this paper, a field-oriented control sheme for an induction motor without speed sensor is presented. For speed control only two current sensors are needed. Experiments have been carried out to show the practicability of this method. The digital control of the drive and the generation of the inverter signals were both made using the VeCon-Chip.

   SYNCHRONOUS MOTOR DRIVES BASED ON DIRECT FLUX LINKAGE CONTROL
By J. Pyrhönen, M. Niemelä, J. Kaukonen, J. Luukko, 0. Pyrhönen; P. Tiitinen, J. Väänänen [View]
[Download]

Abstract: AC-drives based on the Direkte Selbstregelung (DSR) or direct flux linkage control (DFLC) allow high dynamic performance combined with simple control schemes. This paper examines the application of the DFLC-control in synchronous machine drives. Principles of the DFLC-control for electrically excited synchronous machines are introduced.
