Direct Torque Control Strategy of Induction Motors
Direct Torque Control of inverter-fed Induction Machine allows high dynamic performance by means of very simple control schemes. In this paper various direct torque control methodologies as conventional DTC (C_DTC), modified DTC (M_DTC) and twelve sectors (12_DTC) have been analysed and compared in order to evaluate the influence of the motor operating condition on steady state performances. A ...
متن کاملDirect Torque Control of Induction Motor Simulation Using Conventional Method
This paper proposes direct torque control of induction motor simulation using conventional method. Direct Torque Control (DTC) is a control technique used in AC drive systems to obtain high performance torque control and thereby controlling the speed of induction motor. The principle is based on simultaneous decoupling of stator flux and electromagnetic torque of AC drive system. DTC drives use...
متن کاملImproved direct torque control of induction motors using adaptive observer and sliding mode control
This paper presents the synthesis of an adaptive observer which is used for the improvement of the direct torque control of induction motor drives. The observer detects stator flux components in two-phase stationary reference frame, rotor speed and stator resistance by measure of the stator terminal voltages and currents. The observer is adapted using a simple algorithm which does not imply a h...
متن کاملDirect Torque Control Strategy for Dual Three Phase Induction Motors
In this paper, a comparison between a classic direct torque control (DTC) and a modified (DTC) of a dual three phase induction machine (SPIM) will be introduced. In this work, the SPIM has a dual three phase windings spatially shifted by θ electrical degree wich is equal to 60◦. SPIM drive has 64 inverter switching states which provide higher possibility in selecting space voltage vectors than ...
متن کاملA Ripple Minimization Strategy for Direct Torque and Flux Control of Induction Motors Using Sliding Modes
We present a direct torque and flux control (DTFC) design for an electric induction motor using a sliding-mode control technique. A distinctive feature of our approach is that, by appropriately parameterizing and implementing the sliding-mode controller, we explicitely take into account the discontinuous nature of the actuator in the design process. As a result, we obtain an improved implementa...
