ADAPTIVE BANK ANGLE AUTO-PILOT Russian patent published in 2006 - IPC B64C13/18 

FIELD: aircraft instrumentation engineering; manufacture of bank angle auto-pilots for flying vehicles.

SUBSTANCE: adaptive auto-pilot for monitoring bank angle of flying vehicle includes the following components interconnected in series: bank angle setter, first difference unit, first amplifier and second difference unit; servo actuator has output for forming aileron deflection angle; bank rate sensor is connected in series with correcting feedback whose output is connected to second input of second difference unit; bank angle sensor has output connected to second input of first difference unit. Introduced additionally into adaptive auto-pilot are: standard model whose input is connected with output of second difference unit, third difference unit whose second input is connected to output of angular rate sensor, differentiator, second amplifier, summing-up unit whose first input is connected to output of second difference unit and first multiplier unit whose second input is connected with integrator output; integrator input is connected to output of second multiplier unit whose first and second inputs are connected respectively to output of second difference unit and differentiator output.

EFFECT: enhanced dynamic accuracy of bank angle control in wide range of change of flying vehicle parameters due to introduction of combined tuning circuit into auto-pilot.
