Control synthesis for an unmanned helicopter with time-delay under uncertain external disturbances

This paper presents the controller synthesis for an unmanned helicopter with minimum initial information about the parameters of its mathematical model with time-delays of measured and control signals. The unknown parameters, wind disturbances, and system nonlinearity are considered as external disturbances that are estimated using a multi-gap observer. The estimates obtained are used in the control law to improve the stability rate for flight regimes

Synthesis of the correcting control law to improve the helicopter stabilization quality

A single-rotor helicopter with the Ansat-type tail rotor is considered. We solve the problem of synthesizing a correcting law of autopilot control with the use of a observer that permits the quality of stabilizing the specified flight regimes to be improved and pilot’s functional stress to be lowered
