    PV plant integration effect on industrial control applied on DTC-SVM of PMSMG
    (IEEE, 2022) Bourourou, F.; Tadjer, S.; Habi, I.
    this work deals with a new approach based on production power system control strategy based on the Permanent Magnetic Synchronous Generator supplied by inverter connected to PV plant. For that, a mathematical model of the chain simuled on Matlab environment was developed with mixing control techniques, using on load side converter of direct torque control, DTC, based on space vector modulation, SVM, where the PI regulator assure the speed and the DC-bus voltage control. Simulation obtained results of the system are presented and analysed to improve the performance of the used correctors and show performances

    FPGA-based DTC method for three level inverter-fed induction motor speed
    (IEEE, 2017) Douib, Lyamine; Douib, Lyamine; Bencheikh, Fares; Metidji, B.; Kheldoun, Aissa
    The paper presents the natural extension DTC principle of three level diode clamped voltage inverter fed induction motor. This technique is based on a simple algorithm using look-up table for a three-level inverter established from a standard two-level inverter. The control algorithm is implemented using Field Programmable Gate Arrays (FPGA) with VHDL coding

    A novel DTC scheme of double-star induction motors using three-level voltage source inverter
    (2012) Zaimeddine, R.; Berkouk, E.M.
    The objective of this study is to study a new control structure for sensorless Double-Star Induction Motors (DSIM) dedicated to electrical drives using a three-level Voltage Source Inverter (VSI). The output voltages of the three-level VSI can be represented by four groups: the zero voltage vectors, the small voltage vectors, the middle voltage vectors and the large voltage vectors in (d, q) plane. Then, the amplitude and the rotating velocity of the flux vector can be controlled freely. Both fast torque and optimal switching logic can be obtained. The selection is based on the value of the stator flux and the torque. Both approaches, two level control and three level control, are simulated. The results obtained show superior performances over the FOC one without need to any mechanical sensor
