Three-rate neural control of TUAV with coaxial rotor and ducted fan configuration for enhanced situational awareness

This paper describes a critical component of the situational awareness (SA), the control of tactical unmanned aerial vehicle (TUAV) during autonomous flight operations. With the SA strategy, we proposed a three-rate flight control procedure using three autonomous decomposed control subsystems with single NARMA-L2 controller for an unmanned helicopter model with coaxial rotor and ducted fan configuration. This strategy for chosen model of TUAV has been verified by simulation of flight tests using Simulink environment and demonstrated valuable qualities for fast stabilization of TUAV's engines during flight, consequently, fast SA with economy in energy can be asserted during possible missions.
