Abstract: Aiming at the inherent blemish existing currently in airplane cockpit temperature regulating system, a digital temperature auto-regulating design scheme of the system is put forward, namely, a digital proportional-integral-derivative (PID) controller used for temperature control is designed. And then it is applied in airplane cockpit temperature regulating system by adopting the way of cascade control. Experiment results indicate that the design scheme is reasonable and practical.

 

Key words:inherent blemish; digital proportional-integral-derivative (PID) controller; cascade control; auto-regulating
