چکیده
The concept of programmable cascaded low-pass filter method of flux vector synthesis has been introduced in the literature [1]. In this paper, the idea will be expanded, analyzed, improved, and then applied to a stator flux oriented 100-kW electric vehicle drive. It was verified that the flux estimation works well at zero speed finite torque start-up mode and lowand high-speed field weakening regions, thus completely eliminating the need of speed sensor.

Recurrent-neural-network-based implementation of a programmable cascaded low-pass filter used in stator flux synthesis of vector-controlled induction motor drive
The concept of programmable cascaded low-pass filter for stator flux vector synthesis by ideal integration of stator voltages at any frequency was introduced by Bose and Patel. A new form of implementation of this filter is being proposed here that uses a combination of recurrent neural network trained by Kalman filter and a polynomial neural network. The proposed structure is simple, permits f...
متن کاملA start-up method for a speed sensorless stator-flux-oriented vector-controlled induction motor drive
This letter describes a zero-speed start-up method of a speed sensorless stator-flux-oriented direct vector-controlled induction motor drive with the help of a machine current model that does not use any speed signal. The machine starts smoothly with vector control at finite developed torque and then transitions to the standard direct vector-control mode with the voltage model signals as the sp...
متن کاملEvaluation of LPF and PCLPF and Development of a Novel Method to Solve DC Offset Problem in Vector Control of Induction Motors
Stator flux oriented vector control of induction motor (IM) drives for speed sensorless control has several advantages. But the application of a pure integrator for the flux estimation is difficult due to the presence of measurement noise and dc offset. To overcome these problems, some have used a programmable cascaded low pass filter (PCLPF). In this paper, it is shown that some problems still...

متن کاملSpeed-sensorless sliding-mode torque control of an induction motor
Novel induction motor control optimizing both torque response and efficiency is proposed in the paper. The main contribution of the paper is a new structure of rotor flux observer aimed for the speed-sensorless operation of induction machine servo-drive at both, low and high speed, where rapid speed changes can occur. The control differs from the conventional field-oriented control. Stator and ...
