Aeronautical Engineering/PID Temperature controller applications in Aeroplanes.


Dear Jan

Can there be applications of PID temperature controller in Aeroplanes?.


Yes, a modern turbo prop aircraft may use 50-100 PID, jet airliners will use several hundred. The temperature probes are primarily around the engine and fuel system, air conditioning, and cabin environmental control. The PID controllers are usually located in the E&E bay (nose wheel electronics compartment) processing boards.

Rather than having a single dedicated controller. Aircraft are more apt to use polling of several probes by a single controller/cpu.
