Focusing on the improvement and application of integrated navigation algorithm, the research of this paper are separated into two parts: The first part is to construct an appropriate SINS coning error model. The second part is to explore the coning error compensation algorithm. In the first part, the SINS error model and equations are deduced. To evaluate the latter, the coning error compensation...
The BTT flight control system design is researched and established for flight vehicle control mathematical model, control gain solution and mathematical simulation. Firstly, the design of BTT flight control system is put forward, and then a linear controller is designed with fuzzy control theory. Secondly, the flight vehicle's characteristic is analyzed, and the disturbance model is set up. The Frequency-domain...
The ramjet is a new type propulsion system for high-speed flight test aircraft. The ultimate success of sustained high-speed flight will depend on configuring a fine and stable attitude flight control and robust airframe-propulsion-control combination. The mathematical models of high-speed aerodynamic forces and moments were established. A bank-to-turn autopilot structure was used for the longitudinal...
The objective of this paper is to accomplish the modeling and coupling effect analysis of a high-speed aircraft. A 2D model of the high-speed aircraft is assumed. The description of the aerodynamic characteristics including forces and moments system models is included in this paper. The analysis and policies of decoupling are put forward based on the data of the high-speed aircraft. Results show that...
