Improved active disturbance rejection-based full-envelope flight control for a coaxial compound helicopter with multimodal

The coaxial compound helicopter (CCH) system has characteristics such as strong non-linearity, significant coupling, diverse flight modes, as well as control redundancy in the transition mode. This paper proposes a variable-bandwidth extended state observer–based improved active disturbance rejection control (VBADRC) s...
