Abstract ▼ AI-Helper

The vector control technique using low-resolution Hall-effect sensors has been widely used especially in consumer electronics. Due to electrical and/or mechanical unevenness related to binary-type Hall sensors, the calculated or estimated position information has discontinuities so called bumps, which causes the deterioration of vector control performance. In order to obtain a linearly changing position signal from low-precision Hall-effect sensors, this paper proposes a simple bumps in position signal removal algorithm that consists of a first-order observer with low-pass filtering scheme. The proposed algorithm has the feature of no needs for system parameters and additional estimation processes. The validity of the proposed method is verified through simulation and experimental results.

문제 정의

This research is about the performance improvement scheme in position detection for a washing machine. On the other hand, the normal working condition of a washing machine may not be ideal to apply a Luenberger position observer, since the conventional observer schemes require mechanical parameters and the calculation of motor torque in which uncertainty of the motor parameters may exist.

제안 방법

The experiment was performed with a 48-pole SPM motor to demonstrate the performance of the proposed algorithm. Fig.
This paper proposed a new scheme to eliminate the bumps in the position signal using binary-type Hall sensors. The proposed method featured a very simple structure consisting of the first order low-pass filter and the first order observer. The estimated position signal by the proposed method has no phase delay compared to the signals calculated by Hall sensor events.
This paper proposed a new scheme to eliminate the bumps in the position signal using binary-type Hall sensors. The proposed method featured a very simple structure consisting of the first order low-pass filter and the first order observer.
To reduce the order of the observer as well as to remove the involvement of J and T_e in the position estimation procedure, a scheme based only on (3) is proposed in this paper. Since (4) and (5) are used to determine or estimate ω_e for the conventional observer, the proposed scheme is devised to get the estimated motor speed (#, equivalently ω_{e_est}) through a low-pass filter (LPF).
To solve these problems, this paper proposes a new position detection scheme featuring a very simple structure, which obtains linearly changing position information from low-resolution Hall sensors without employing system parameters. The proposed scheme does not require calculation of either the motor torque or the load torque.
