| Popis: | 92 The control of flight vehicles has been an important topic ever since the range of activities of human beings was extended from the earth to the universe. The decision part in an airframe: guidance law (GL) and autopilot are being discussed, and the intercepting missiles and launch rockets are the two plants we are interested in. In this thesis, we advocate a wingless airframe in order to reduce the nonlinear effect from the aerodynamics as much as possible. We propose a robust autopilot system based on thrust vector control (TVC) and divert control system (DCS) in order to extend the maneuvering range of an airframe from the place with aerodynamic influence to the place without. Besides, two new missile GLs and one original rocket GL are presented. The missile GLs utilize the optimal control theory, feedback linearization technique, and Lyapunov analysis, whereas the rocket GL employs the differential geometry and sliding mode control. In addition, the design methodology of parameters of the integrated guidance/autopilot (G/A) systems is suggested with technical proofs. Various simulations including aerodynamic model were finally demonstrated to verify the feasibility of the integrated G/A systems of missiles and rockets. |
