Research on Adaptive Fault Diagnosis Control System of Audio Management Component Environment of Airborne Electronic Equipment

The system adopts adaptive control, and the controller of audio management component is directly applied to controlled object. Through online calculation, model identified by using dynamic characteristics object, relationship between input output variables expressed. It can be corrected entering leaving data, which actually correct controller. initial rules are composed default models. continuous self-reasoning learning, optimized achieve data tracking, fast convergence, strong anti-interference ability excellent performance. Combining intelligent control with technology not only expands scope system, but also provides an effective way for control. environmental diagnostic uses adjust parameters, knowledge base detects IO signal, AD signal status sent sub-unit through internal CAN bus according power-on self-check unit, at same time, it monitors all in real time during operation, judges operation each sub-component, gives alarm carries out protection design integrated detection module, overall installation space sensors reduced, interfaces connecting cables diagnosis effect improved. recording storage function, stores information subunit, compares built-in health table, prompts maintenance time.
