Abstract
According to various advantages of linear
induction motor (LIM), such as high starting thrust force,
high speed operation and reduction of mechanical losses,
more applications have utilized this type of motors. Direct
Thrust Control (DTC) technique is considered as one of the
most efficient techniques that can be used for LIM. DTC is
preferable to give a fast and good dynamic thrust response.
So, to improve the accuracy and robustness of contouring
control for CNC machine tools, linear induction motors with
a direct thrust control technique are introduced for driving
these machines. An industry standard motion control system
is applied for reducing the tracking error and improving the
desired accuracy. Different loading conditions are simulated
to validate the reliability and robustness of the introduced
system to match the application field. The proposed system is
simulated using the MATLAB/SIMULINK Package;
simulation results validated both tracking accuracy and
robustness of the proposed motion control system for
contouring control for a CNC (Computer Numerical
Control) milling machine.
