“…Similarly, a non-smooth control approach applied to permanent magnet synchronous motor (PMSM) DTC is found in study [26], which includes a real-time disturbance observer to estimate the disturbed parameters (friction and load torque, etc. ); an observed value is used as an estimate for compensation of localized system disturbances.…”

This paper presents a study focused on the operation of a twelve-sector direct torque control (DTC) structure under both healthy and faulty conditions for an induction motor (IM). The fault-tolerant control (FTC) discussed herein pertains to a three-phase two-level inverter based on an open-circuit fault of an insulated gate bipolar transistor (IGBT). In this scenario, the gate signal of the transistor is manually forced to zero. The proposed control mechanism is capable of maintaining stability at a certain minimum performance level. Experimental results, derived from testing the IM under both healthy and faulty modes using a Dspace 1104 board, display the commendable performance of the proposed control. This improved DTC strategy, bolstered by twelve sectors, has resulted in minimizing torque ripples, flux, and stator current oscillations, as compared to conventional DTC. The principle provides a robust solution that effectively reduces vibrations and audible noise.

“…The third equation of Equation( 1) shows that stator magnetizing current i md and i mq can be expressed by iron loss resistance R f and stator current i d and i q . In other words, if the R f can be estimated, then i md and i mq can be estimated through equation (5). When the estimated iron loss resistanceR f converges to the actual R f , the estimated stator magnetizing current i md_est and i mq_est is also equal to the actual i md and i mq .…”

This paper proposes a direct torque control (DTC) of permanent magnet synchronous motor (PMSM) with high torque estimation accuracy. Based on the PMSM mathematical model considering iron loss resistance, this paper analyzes that when using stator current to estimate torque, the accuracy will be affected by iron loss resistance. Using stator magnetizing current can solve the current deviation caused by iron loss resistance and improve torque estimation accuracy. Since the stator magnetizing current cannot be obtained directly, a novel iron loss resistance observer based on the model reference adaptive system (MRAS) is designed to estimate iron loss resistance and stator magnetizing current simultaneously. Popov's hyperstability theory guarantees the stability of the designed observer. Finally, a 1kW PMSM experimental platform is constructed to verify the proposed method. Both the simulation and experimental results show that the designed observer is stable, and using stator magnetizing current to estimate torque has better accuracy than stator current.

“…Interior permanent magnet synchronous machines (IPMSM) have many attractive advantages such as high efficiency, high power/torque density [1]- [3], high reliability and good field-weakening performance [1], [4], therefore, it has been used in plenty of industrial applications, such as robot motion control, electric vehicles and other industrial fields [5], [6]. In order to control IPMSM drives, in literature, both field orientated control (FOC) in the rotor reference (d-q) frame [7]- [9] and direct flux vector control (DFVC) in the fluxtorque (f-t) reference frame [10]- [13] have been proposed to achieve MTPA control in constant torque region [14], [15] and field weakening operation in constant power region [16], [17].…”

In this paper, the drawbacks of the conventional f-t frame based maximum torque per ampere (MTPA) control schemes are analyzed and mathematically proved. In order to inherit the merits of both the direct flux vector control (DFVC) in field weakening region and field orientated control (FOC) in constant torque region while avoiding their disadvantages, an integrated control scheme is proposed. The proposed control scheme integrates the FOC into f-t reference frame at low speeds to achieve a relatively accurate and robust MTPA control, while at high speeds, the DFVC is adopted to utilize the advantages of f-t frame based control scheme in field weakening region. A shape function is utilized by the proposed control scheme to achieve a smooth transition between the two control schemes. The proposed control scheme is verified by experiments under various operation conditions on a prototype IPMSM drive. The simulation and experimental results illustrate that the proposed control scheme could achieve a better MTPA control accuracy in constant torque region and a better field weakening performance in the constant power region. Meanwhile the complex look-up tables for FOC in field weakening region and the difficulties in observing flux vector at low speed are avoided. INDEX TERMS Maximum torque per ampere (MTPA) control, Direct flux vector control (DFVC), Field orientated control (FOC), Interior permanent magnet synchronous machine (IPMSM), Torque control.
