Energy Efficient Control of an Induction Machine under Load Torque Step Change
Optimal control of magnetizing current for minimizing induction motor power losses during load torque step change was developed. Original problem was slightly simplified and exactly optimal control was obtained for modified formulation. Obtained strategy has feedback form and is exactly optimal for ideal speed controller performance and absence of saturation in motor. Then original and simplifi...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولImproved Direct Torque Control for Induction Machine Drives Based on Fuzzy Sector Theory
Here, a new fuzzy direct torque control algorithm for induction motors is proposed. As in the classical direct torque control, the inverter gate control signals directly come from the optimum switching voltage vector look-up table, the best voltage space vector selection is a key factor to obtain minimum torque and flux ripples. In the proposed approach, the best voltage space vector is sel...
متن کاملModified Look-Up Table for Enhancement of Torque Response in Direct Torque Controlled Induction Machine
Received Mar 2, 2017 Revised May 2, 2017 Accepted May 15, 2017 Basically, the direct torque control (DTC) drive system is operated at light load. At light load, supplying the drive system with rated flux will decrease the efficiency of the system. To maximize the efficiency of drive system, an optimal flux has been applied during steady-state but when a torque is suddenly needed, for example du...
متن کاملImplementation of direct torque control of induction machine utilising TMS320C31 digital signal processor
Recently, digital signal processors (DSP's) are becoming more popular in the area of ac motor control, in particular the induction motor drives. The fast number crunching capabilities of DSP's which are traditionally meant for data processing tasks such as image processing and speech recognition, are being utilised to perform on-line calculation of the ac motor variables, such as electromagneti...
