“…However, the EV drive system mainly operates in torque-control mode and the speed functions only in an auxiliary role. Therefore, torque performance, including steady-state response and dynamic response, is important for the EV drive system [11], [30]. Although a DTC scheme has good robustness, factors such as inverter dead-time and flux observer can still affect the system, particularly at low speeds [14], [19].…”

A modified direct torque control (DTC) method based on torque angle is proposed for interior permanent-magnet synchronous motor (IPMSM) drivers used in electric vehicles (EVs). Given the close relationship between torque and torque angle, proper voltage vectors are selected by the proposed DTC method to change the torque angle rapidly and regulate the torque quickly. The amplitude and angle of the voltage vectors are determined by the torque loop and stator flux-linkage loop, respectively, with the help of the position of the stator flux linkage. Furthermore, to satisfy the torque performance request of EVs, the nonlinear dead-time of the invertor caused by parasitic capacitances is considered and compensated to improve steady torque performance. The stable operation region of the IPMSM DTC driver for voltage and current limits is investigated for reliability. The experimental results prove that the proposed DTC has good torque performance with a brief control structure.

“…High-performance control strategies for IPMSMs mainly include field-oriented control (FOC) and direct torque control (DTC) [11]- [29]. FOC simplifies the IPMSM into equivalent DC motors by coordinate transformation and uses quadrature and direct axis currents as control objects.…”

“…At lower speeds, the sinusoidal switching pattern should be employed, as shown in Fig.2. To avoid torque discontinuity, switching between these patterns must be done seamlessly [6]. However, for traction applications, the motor drive needs a fast torque response with a straightforward mechanism.…”

Electric drive vehicles (EDV) have received much attention recently because of their environmental and energy benefits. In an EDV, the motor drive system directly influences the performance of the propulsion system. However, the available DC voltage is limited, which limits the maximum speed of the motors. At high speeds, the inverter voltage increases if the square wave (SW) voltage (six-step operation) is used. Although conventional direct torque control (DTC) has several advantages, it cannot work in the six-step mode required in high-speed applications. In this paper, a single-mode seamless DTC for AC motors is proposed. In this scheme, the trajectory of the reference flux changes continuously between circular and hexagonal paths. Therefore, the armature voltage changes smoothly from a high-frequency switching pattern to a square wave pattern without torque discontinuity. In addition, because multi-mode controllers are not used, implementation is more straightforward. Simulation results show the voltage pattern changes smoothly when the motor speed changes, and consequently, torque control without torque discontinuity is possible in the field weakening area even with a six-step voltage pattern.

“…Traditionally, the DTC algorithm is executed using a Digital Signal Processor (DSP) [13][14][15], with code written using Cprogramming or a graphical programming approach, a much simpler method, appropriate for rapid prototyping. It should be noted that the sampling frequency of the processor depends on the computational burden.…”
