A method of separation of an aircraft motion on a roll and sideslip

The requirements to maneuver a modern aircraft involve the development and realization of advanced control of a longitudinal and lateral aircraft motion. The manual control system for independent motion control of an aircraft on rolling and sideslip angles is studied. The system depends upon a real‐time measurement of air‐dynamic coefficients of the aircraft or requires the information from the tabulated parameters on all regimes of the aircraft motion. The exact parameters for all regimes of the aircraft motion cannot be obtained from a priori measurements either. In this paper, the solution for a decoupled motion of an aircraft is obtained in the class of non‐searching adaptive control systems with a reference model. The new algorithms developed in this paper achieve a decoupled motion with desirable dynamic precision even in conditions of high non‐stationary of parameters. The robustness of the control system to the interaction of subsystems is accomplished as well.
