The application of the 3 phase induction motor is increasingly developing, this has led to research on speed regulation motors also growing, because use in industry and especially hybrid vehicles being developed. However, there are several disadvantages an motor, one which non-linear parameter characteristics, rotor resistance, varies value for different operating conditions, so that it cannot ...
Mechatronic systems are complex interdisciplinary products where many parts are present that overlap each other; electronic control board, electromechanical machines, and power drives. With FPGAs, their control can run faster as multiple operations are executed in parallel. A simulation tool that facilitates the direct translation into hardware of mechatronic control algorithms is desirable. Th...
Induction machine drive based on Direct Torque Control (DTC) allows high dynamic performance with very simple hysteresis control scheme. Conventional Direct Torque Control (CDTC) suffers from some drawbacks such as high torque ripple and variable switching frequency , difficulties in torque as well as flux control at very low speed. This paper is aimed to analyze DTC principles, the strategies ...
Since induction motors were invented, human civilization has changed forever. Due to their beneficial characteristics, are widely used and have become the most prevalent electrical counterparts. Many control strategies for been developed, varying from scalar vector control. In class of control, Direct Torque Control (DTC) was proposed as an alternative that ensures separated flux torque while r...
The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers the three phase system as three independent systems the control will remain analog and thus present several drawbacks. Since high computational power silicon devices, such as the TMS320F240 from TI, came...
By rapid development of semiconductor and commands strategies as vector control (VC), direct torque control (DTC) and input-output linearization (IOL) a permanent magnet synchronous motors (PMSM) have gained variety industrial applications. This paper combines the application of neuro-genetic (NG) with input-output linearization techniques to control the PMSM. The use of a genetic algorithm is ...
In this paper, we propose two approach intelligent techniques of improvement of Direct Torque Control (DTC) of Induction motor such as fuzzy logic (FL) and artificial neural network (ANN), applied in switching select voltage vector .The comparison with conventional direct torque control (DTC), show that the use of the DTC_FL and DTC_ANN, reduced the torque, stator flux, and current ripples. The...
This paper proposes a new direct power control (DPC) for wind turbine system driven by doubly fed induction generator (DFIG) in order to track maximum absorbable power in different wind speeds. New DPC employs input- output linearization and sliding mode nonlinear controller for robust control of active and reactive power to obtain maximum power from wind turbine. As the three phases voltages w...
