This research investigates the acceptability of
the Artificial Neural Networks (ANN) over the PID
Controller for the control of the Magnetic Levitation
System (MLS). In the field of advanced control systems,
this system identifies as a feedback-controlled, single
input- single output (SISO) system. This SISO system
used a PID controller for vertical trajectory controlling
of a metal sphere in airspace by using an
electromagnetic force that directed to upward. The
vertical position of the metal sphere controlled
according to the applied magnetic force generated by a
powerful electromagnet and the electromagnetic force
controlled by varying the supply voltage. To control this
nonlinear system, we develop a multilayer artificial
neural network by using Matlab software and integrate
that with the physical magnetic levitation model.
According to specific initial conditions, the actual
responses of the magnetic levitation system with
artificial neural network compares the desire response
of the metal sphere. The ability of control this nonlinear
system by using neural networks validate by comparing
results obtained by the PID controller and artificial
neural network.
