Speed control of high speed aircraft with fixed attack angle and constant elastic shape states

Abstract

Abstract. For high speed vehicles, the engine model is difficult to built. Also it is very important and difficult to design a proper oil supplying law to make the speed of control object to tracking the desired value as accurate as possible. So a kind of speed controller is designed based on the pitch channel model built according to Lagrange equation and released by USA force. Since the speed of this flying object is too high, to make the question simple, a kind of virtual flying condition is proposed such that the design of speed controller can be simple and easy to verify. So the attack angle is assumed to be constant and the elastic shape states are also assumed to be a constant. And this virtual flying design method can not only make the speed controller design simple, it can also make it is possible to testify the rightness of the engine model with the help of numerical simulation technology.
