A Novel Dynamic Overmodulation Strategy of Direct Torque Control
The direct torque control-space vector modulation (DTC-SVM) is well-known for achieving excellent dynamic overmodulation. However, the method uses complicated predictive stator flux vector control and requires high precision stator flux vector to define overmodulation mode. This paper proposes a straightforward dynamic overmodulation method and constant switching frequency controller without SV...
متن کاملDirect 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 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 کاملTorque Ripple Minimization Strategy for Direct Torque Control of Induction Motor Using Fuzzy Scheme
The direct torque control (DTC) speed control scheme of an induction motor surpasses the vector control in the sense that it controls the torque directly and does not use transformations and current modulator. In the traditional direct torque control (DTC) of induction motor, the low order harmonic component of stator current is very large when the motor is running at low speed. It leads to hig...
متن کاملA Novel Hybrid Droop-Isochronous Control Strategy for Microgrid Management
The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...
