Research on robust stability of control systems aircraft
AbstractThis paper investigates robust stability control systems aircraft, built in the three-parameter classes of structurally stable maps with control law, given in the form of disaster “hyperbolic umbilic”. Stability analysis is based on linear approximation and the use of algebraic Hurwitz criterion. It is shown that the introduction of the control law in the form of disaster “hyperbolic umbilic” motion control system of the aircraft becomes resistant to external disturbances and noise in all the unknown parameters of the object control and set parameters of the regulator. The results are confirmed by numerical experiment conducted on the basis of the program complex Vissim 6.0.
