Full Motion Flight Simulation Platform
Platform controller
The platform controller receives positioning information from the
Motion-Base driver software and has to take care of moving each
cylinder to the desired length.
Controller hardware
The controller hardware is based on Motorola's
68HC12 chip.
A completely assembled board
with this chip is available from a German company named
Elektronikladen, but of course
any other board will do just as well.
A second board will be designed which holds the peripheral driver
chips to control the pneumatic valves, and any necessary I/O connectors.
Controller software
This is probably the single most complicated thing in the entire project.
With a hydraulic cylinder you pump in as much hydraulic fluid as desired
and the piston will move to its target position and stay there, independent
of the forces that are applied to it. With a pneumatic
cylinder a compressible medium is used to move the piston, so any change
in the forces applied to the piston will result in a change of its position.
This makes the whole problem highly dynamic, and I believe the only way
to solve it is to use Fuzzy Logic.
Tools
The compiler used to build the controller software is the ICC12 C Compiler from
ImageCraft.
Status
The controller board using Motorola's 68HC12 chip is operative, and the peripheral
controller hardware for one cylinder has been set up on a "breadboard".
Now the software to implement the fuzzy control algorithm has to be written.
