SYSTEM FOR CONTROLLING PILOT-FREE AIRCRAFT BY ROLL AND PITCH ANGLES Russian patent published in 2005 - IPC

FIELD: board systems for automatic control of aircrafts with circuit for realizing modes of turnings in lengthwise circuit at large pitch angles and coordinated turnings in lateral circuits at large roll angles.

SUBSTANCE: system includes controlled object, first and second actuating devices, pitch angle pickup, pickup of angular velocity according to pitch angle, roll angle pickup, pickup of angular velocity according to roll angle, setters for pitch and roll angles, setters of reference signal for pitching and rolling circuits, two comparators, two units for separating positive polarity signal, two summing amplifiers, two units for extracting modulus, two relay units with dead zone, AND gate, controlled switch, four limiters, two adders.

EFFECT: enlarged functional possibilities of system due to changed control level in one circuit at condition of real unloading of adjacent circuit, enhanced accuracy of system.
