“…Vector control (VC) and direct-torque control (DTC) belong to the high-performance control strategies. VC lays the theoretical foundations for high performance AC speed control, realizes the decoupling control of magnetic field and torque, but VC requires an accurate IM model [2]. However DTC does not require complex coordinate transformations and large system calculations, has improved IM control system performance, but has a large torque ripple at low speed [3].…”

Induction motor (IM) is a complex controlled object that is difficult to drive and control. In this paper, direct torque control strategy (DTC) is adopted to drive IM. In order to overcome drawbacks of the bad low speed performance of DTC system, Tornambe control (TC) is used to replace the traditional speed regulator to improve system performance. The results show that TC strategy overcomes the disadvantage of the low speed performance declined and improves the response speed of DTC system, and effectively solves the contradiction between the system response speed and overshoot.

“…The control method and drive strategy of PMSMs are complex. The three main PMSM drive strategies are constantfrequency ratio control (VVVF), field-oriented control (also called vector control (VC)) [1], and direct-torque control (DTC). VVVF is called a variable-voltage and variable-frequency control; this strategy mostly adopts open-loop control [2] and has a simple structure.…”

The permanent-magnet synchronous motor (PMSM) is a complex controlled object that is difficult to drive and control. In this study, the vector control strategy is adopted to drive the PMSM. The active disturbance rejection controller is used to achieve the closed-loop control of PMSM, which simplifies the computational complexity. A load torque observer and feedforward compensation component are designed to overcome the PMSM speed fluctuation of the load disturbance. An experimental system based on the DSP board is designed to test the controller performance. The results validate the control algorithm.

“…Several novel DPWMs with double injections are analyzed in [17] to obtain minimum current harmonic or minimum switching loss. A feedback quantization modulator [18] is applied to a permanent-magnet synchronous motor (PMSM) drive system to show a 33% reduction in switching number in contrast to SVPWM in [19]. The minimum-switching-loss PWM proposed in [20] can reduce up to 36% of switching loss.…”

An error-compensated pulse width modulator (ECPWM) is proposed to improve the baseband harmonic performance and the switching loss of voltage source inverters (VSIs). Selecting between harmonic distortion and switching loss is a design tradeoff in the conventional space vector pulse width modulation. In this work, an accumulated difference in produced and desired phase voltages is considered to adjust the reference signal. This mechanism can compensate for the voltage error in the previous carrier period. With error compensation every half-carrier period, the proposed ECPWM allows one-half reduction in carrier frequency without scarifying baseband harmonic distortion. The proposed modulator is applied to a three-phase VSI with R-L load and a motor-speed-control system for experiments. The measured efficiency and operating temperature of switches confirm the effectiveness of the proposed scheme.
