“…According to (12) and (14), there are two differences between the S-DTC and FS-DTC: the switching period (T sw_S and T sw_FS ) and the amplitude of the stator voltage vector (U s_S and U s_FS ), which result in different performances. In this section, the maximum speed, torque ripple, and response time of the torque are compared.…”

“…It is known that ΔT S_max and ΔT FS_max are the torque changes during one switching period while the equivalent switching period of the FS-DTC T sw_FS is different from the switching period of the S-DTC T s_FS . Therefore, according to (12) and (21), the change rate of the torque can be given by:…”

“…Therefore, many efforts have been made to minimize the number of current sensors for electric drive systems. In [10]- [12], several current-sensorless control methods are presented. Although the cost of the drive systems is reduced significantly without current sensors, their dependence on accurate electric machine models weakens system robustness.…”

This paper presents a fast switching direct torque control (FS-DTC) using only a single DC-link current sensor. In FS-DTC, six new active voltage complex space vectors (CSVs) are synthesized by the conventional active voltage space vectors (SVs). The corresponding sectors are rotated in the anticlockwise direction by 30 degrees. A selection table is defined to select the CSVs. Based on the "Different Phase Mode", the output sequence of the selected CSV is optimized. Accordingly, a reconstruction method is proposed to acquire the phase currents. The core of the FS-DTC is that all of the three phase currents can be reliably reconstructed during every two sampling periods, which is the result of the fast switching between different phases. The errors between the reconstructed and actual currents are strictly limited in one sampling period. The FS-DTC has the advantages of the standard DTC scheme such as simple structure, quick torque response and robustness. As can be seen in the analysis, the FS-DTC can be thought of as an equivalent standard DTC scheme with 86.6% of the maximum speed, 173.2% of the torque ripple, and 115% of the response time of the torque. Based on a dSPACE DS1103 controller, the FS-DTC is implemented in an induction machine drive system. The results verify the effectiveness of the FS-DTC.

“…The EM control scheme we propose (see [1]) is reported in Figure 3. The "Speed Controller" is used only during start-up, warm-up and switching-off phase, whereas during the power generation phases the input of the EM control is directly the reference torque by passing the speed controller (see Figure 2).…”

The control of a typical Auxiliary Power Unit for series type hybrid electric vehicles is considered. The APU is equipped with an internal combustion engine and with an electrical induction motor used as starting motor and as battery charging generator. Dynamic models of both engine and motor are considered and exploited for the design of the APU controller. A field oriented control scheme and a decoupling controller with two independent current control loops is used for the motor whereas a torque controller regulates the engine transients. The control of the whole APU is thus designed by coupling the engine and motor controllers through a cascaded feedback control approach. Different APU control strategies are used depending on the shaft speed and on the power requested by the battery management system. Simulation results are carried out with Matlab/Simulink. Small oscillations in the battery charging current and small power tracking error confirm the effectiveness of the proposed controller both in steady state and during transients.

High-performance vector control without AC phase current sensors for induction motor drives: Simulation and real-time implementation

et al. 2021

The main purpose of this paper is to develop a high-level performance, and low-cost current sensorless control strategy for Induction Motor (IM) drives. Therefore, a new phase-current regeneration method, for current sensorless vector control in induction motor drives is introduced. The idea is based on the reconfiguration of the Luenberger adaptive observer for currents estimation, using the information provided by the dc-link voltage sensor. The basis of the proposed control and the theoretical study of the modified adaptive observer are presented. Several simulation and experimental tests were performed on an induction motor of 1.1 kW working under different operating conditions. The obtained results prove and testify the relevance, workability, and practicability of the suggested currents sensorless vector control strategy.
