“…In spite of these advantages, this method suffers from high torque and flux ripples, as well as variable switching frequency. In recent years, different schemes have been proposed to enhance the performance of the conventional DTC method (Ismail et al, 2017;Jidin et al, 2017;Jannati et al, 2013).…”

In this paper, a novel hybrid Direct Torque Control (DTC) strategy based on predictive control with optimization of the Proportional-Integral (PI) controller to improve overall performances of Three-Phase Induction Machine (TPIM) drives is proposed. The presented control technique has contained merits of the DTC method such as fast dynamic response, simple structure, less dependence to machine parameters and merits of vector control method such as high accuracy. Furthermore, a hybrid DTC method with optimal voltage vectors is presented. In the proposed control system, Genetic Algorithm (GA) is employed to obtain optimal values of the PI controller parameters. Finally, simulation results under the presented control strategy showed good performances of this method in comparison with DTC and vector control techniques.

“…The basic idea of this technique is a direct command of the stator flux and torque of IM without any pulse width modulation (PWM) strategy and proportional-integral (PI) controllers. However, this method is a simple structure compared to the field-oriented control (FOC) strategy and Scalar Control (V/f) [6,7]. In this method, the switching table is used to control the inverter.…”

<span>This article presents an improved Direct Torque Control (DTC) technique with space vector modulation (SVM) for a five-phase permanent magnet synchronous motor (PMSM) using a sliding mode speed control (SMC).The proposed control scheme of the five-phase PMSM combines the advantages of SMC control and the SVM algorithm. The SMC method insensitive to uncertainties, in particular external disturbances and parameter variations. In this paper, the SMC controller is used to control the rotor speed of the five-phase PMSM based on DTC-SVM. The rotor speed response, torque and stator flux are determined and compared with traditional control method. The simulations results confirm the validity and effectiveness of the proposed control technique in terms of performance and robustness against machine parameter variations (inertia variation). The efficiency of the proposed method applied on the five-phase PMSM is verified by the MATLAB/Simulink.</span>

Model predictive torque control (MPTC) is developing as a high-performance control system for 3φ induction motor (IM) drives due to its simple structure and fast dynamic response. This paper proposes a sensorless modified MPTC (MMPTC) strategy to control the speed of 3φ IM drives. The suggested scheme uses an improved model reference adaptive system (MRAS) to estimate the rotor speed, motor fluxes, and improvement of the prediction model of the controller. Many experimental and simulation results using DSP/TMS320F28335 controller board and Matlab software are presented to validate the proposed control method. In addition, a comparative study for the traditional sensorless MPTC and proposed MMPTC is experimentally investigated. The presented results show low speed, torque, and flux ripples of the suggested MMPTC system at low-and high-speed ranges.
