Description: sensorless induction motor drive is presented, in
which the principles of sliding-mode control, direct torque control
(DTC), and space-vector modulation are combined to ensure
high-performance operation, both in the steady state and under
transient conditions. Merits of the classic DTC transient behavior
are preserved, while the steady-state operation is significantly improved.
The torque and flux controllers, and motor state observer
are of the sliding-mode type. The inverter is directly controlled on
the basis of torque and flux errors, using space-vector pulsewidth
modulation. Computer simulations and experimental Platform: |

Description: 1Abstract—Today, linear induction motors spread out in the
field of transportation and many industrial fields such as
railway and electromagnetic launcher systems. Especially, high
efficiency control and fast dynamic response are demanded for
electromagnetic launcher systems and it’s well known that
direct torque control scheme provides fast dynamic response
for rotary induction motors. This paper describes Simulink
model of direct thrust controlled linear induction motor with
end effect for electromagnetic launcher system and presents a
simple and effective scheme for direct thrust control of a linear
induction motor. The Simulink model of single sided linear
induction motor with end effect developed to realize the direct
thrust control. To show the effectiveness of the improved
system, simulation results are presented using commercially
available software package Matlab/Simulink. Platform: |
