Design and Analysis of Coordinated Bank-to-Turn (CBTT) Autopilots for Bank-to-Turn (BTT) Missiles

摘要

This work addresses the design and analysis of the Pitch, Yaw and Roll autopilot for application to the Bank-to-Turn (BTT) missiles. At first, the linear uncoupled channels were designed and analyzed according to the desired requirements. Utilizing the uncoupled channels, the linear coupled autopilots were designed, not including the inertial, kinematic and aerodynamic cross-coupling. Then, the nonlinear CBTT autopilots were designed and analyzed, using the linear CBTT (Coordinated Bank-to-Turn) models, which now have coupled with kinematic, inertial and aerodynamic cross-coupling. The minimization of the above kinematic and inertial coupling and their effects were completed using feedbacks of angle-of-attack and rate of angle of attack in the Pitch autopilot. (Author)
