Abstract-Direct I. INTRODUCTIONInduction motors are the most widely used alternative in adjustable speed drives. Field Oriented Control (FOC) [1], and Direct Torque Control (DTC) [2,3] have emerged as the standard industrial solutions for high dynamic performance operation of these machines.In particular DTC offers attractive performance in terms of fast torque response, simple and less computational cumbersome control schemes, robustness against parameter variation, no need of PWM modulator and current regulators. However it has some draw backs like torque ripple, variable switching frequency, electromagnetic compatibility due to high frequency harmonic current and voltage. In recent years, research is going on DTC for multi level converters [5,6,9] attractive solution for high power applications, due to higher voltage operation capability, reduced common mode voltages, near sinusoidal outputs, low dv/dt's and smaller or even no output filter [4]. The most attractive features of this technology are in the medium to high-voltage application range (2-13 kV), which include motor drives, power distribution, power quality and power conditioning applications [13]. One of the advantages of multilevel inverters is that the voltage stress on each switching device is reduced. In addition, multilevel waveforms feature have less harmonic content compared to two level waveforms operating at the same switching frequency .In multi level inverters, it is easy to reach high voltage levels in high power applications with lower harmonic distortion and switching frequency, which is very difficult to get this performance with conventional two level inverters. The high-voltage switches are rather expensive, the employment of the double number of the cheaper switches are often economical favorable. Simultaneously the less IM current and torque distortions can be achieved by using of the more number of the feasible inverter states [9].In this paper two different DTC schemes will be compared with each other. These two schemes are DTC-SVM with two-level inverter and DTC-SVM with threelevel inverter. The Proposed scheme is described clearly and simulation results are reported to demonstrate its effectiveness. The entire control scheme is implemented with Matlab/Simulink. II. DTC-SVM WITH TWO-LEVEL INVERTER A. Vector Model of Inverter Output VoltageIn the PWM voltage source inverters, considering the combinations of the states of switching functions inverter switching state functions (C1, C2, and C3) which can take either 1 or 0, the voltage vector becomes.Eight switching combinations can be taken according to the above relationship: two zero voltage vectors and six non-zero voltage vectors show by Fig.2 [1][2]. B. Stator Flux and Torque EstimationThe components of the current (Isα, Isβ), and stator voltage (Vsα, Vsβ) are obtained by the application of the transformation given by (5) and (6)

By using the direct torque control (DTC), robust response in ac drives can be produced. Ripples of currents, torque and flux are oberved in steady state. space vector modulation (SVM) applied in DTC and used for a sensorless induction motor (IM) with fuzzy sliding mode speed controller (FSMSC) is studied in this paper. This control can minimize the torque, flux, current and speed pulsations in steady state. To estimate the rotor speed and stator flux the model reference adaptive system (MRAS) is used that is designed from identified voltages and currents. The FSMSC is used to enhance the efficiency and the robustness of the presented system. The DTC transient advantage are maintained, while better quality steady-state performance is produced in sensorless implementation for a wide speed range. The drive system performances have been checked by using Matlab Simultaion, and successful results have been obtained. It is deduced that the proposed control system produces better results than the classical DTC.
