Unmanned helicopter pre-design and analysis

, 2021
İnsansız helikopter tasarım süreci farklı metotlarla işleyebilir. Bu metotlar üreticiden üreticiye değişir. Bu tezde maksimum kalkış ağırlığı için ilk yaklaşık değer, faydalı yük maksimum kalkış ağırlığı oranının 0.5 ile 0.55 arasında olması gerektiğini belirten ideal helikopter yaklaşımı kullanılarak bulunur. Bu bulunan maksimum kalkış ağırlığı benzer

Active modeling based model predictive control for yaw-heave coupling dynamics of unmanned helicopters in full flight envelope

, 2009
For realizing the yaw-heave coupling control of unmanned helicopters in full flight envelope, an active modeling based controller is developed based on robust model predictive control and adaptive set-membership filter estimation.
