“…Using the extended transfer function (9) (10) , the both disturbance suppression characteristics of d-q PI current control and α-β sinusoidal current control are evaluated in this paper by using the extended transfer function, which is introduced in Appendix of this paper. The extended transfer function can evaluate the both frequency characteristics of d-q PI regulator and α-β-sinusoidal regulator on the positive and negative harmonics phase components.…”

Stationary Reference Frame Position Sensorless Control Based on Stator Flux Linkage and Sinusoidal Current Tracking Controller for IPMSM

Generally, standard direct torque control (DTC) does not require fine current responses from the current controller because the torque and flux of a DTC-based drive are controlled by a closed-loop system without current loops. It is often difficult for the standard DTC to achieve the desired current regulation and fine harmonic current disturbance suppression performancew. In order to overcome these problems, this paper proposes a new stationary reference frame position sensorless control system based on stator flux linkage estimation, and a new sinusoidal current tracking controller. In this paper, the current control performance of IPMSMs using the proposed sinusoidal current tracking controller is evaluated through numerical simulation and experiments. Finally, using the proposed sinusoidal current tracking controller, the effectiveness of the proposed stationary reference frame position sensorless control system with the stator flux control method is confirmed through experimental results.

“…Analytical results rather than intuitive discussions on properties of the filter with vector rotator have already been obtained: analyses were carried out using extended transfer function and extended Bode diagram by Nakano and colleagues, who employed first-order high-pass filters as interior parallel arranged filters [16][17][18]. Other analysis where first-order low-pass filters were employed as interior paral-lel arranged filters was performed in relation to control of magnetic bearing systems by Murakami [21].…”

SUMMARYSignal processing based on frequency polarity has been attracting wide attention due to its potential applications to industry. It is popular to employ two vector rotators for such signal processing. However, it has very recently been reported that an equivalent signal processing effect can be attained in a much simpler manner using two-input two-output filters in the D-module. This paper further investigates a class of characteristic-varying systems in the D-module, which contains the filters in the D-module as a special case, and gives new analytical results on their properties from the viewpoints of existence, realization, and stability. If the results are applied to filter problems, n-th order filters in the D-module in new forms can be easily and directly obtained, whose stability and response equivalent to the associated filters with vector rotators are guaranteed. If the results are applied to AC motor modeling problems, dynamic models and block diagrams of AC motors in general reference frame are easily and directly obtained. Very general and useful analyses are given for a newly proposed class of characteristic-varying systems in the D-module that have potential usefulness in various industrial applications including control of magnetic bearing system, analyses and active compensations of power systems, and sensorless drives of AC motors.
