Abstract

The invention relates to the simulation and the verification of a control method in the field of aerospace. In order to provide a simulation and verification platform capable of supporting a near space aircraft to real-time simulation tests and performance evaluation from the design of a flight control system, the technical scheme adopted by the invention is as follows: a simulation and verification method of the control method of the near space aircraft is realized by virtue of the following devices: a simulation master control machine and a dSPACE real-time simulation machine, wherein the simulation master control machine is provided with a DS817 high-speed serial communication interface plate; and the simulation master control machine is communicated with the DS814 high-speed serial communication interface plate of the dSPACE real-time simulation machine through an optical fiber. The method comprises the following steps of: operating master control software; dividing a whole evaluation process into two parts, namely a control system efficiency evaluation process and an evaluation confirmation process, by performance evaluation software; and obtaining data, which is needed by control system efficiency evaluation, by the control system efficiency evaluation process through three steps. The simulation and verification method of the control method of the near space aircraft is mainly applied to simulation and verification in the field of aerospace.

Description

technical field [0001] The invention relates to a control method simulation and verification problem in the aerospace field. Specifically, it is the real-time simulation and performance evaluation verification of the control method of the near-space vehicle. In particular, it relates to a simulation and verification platform for a control method of a near-space vehicle. Background technique [0002] Due to the special airframe / engine integrated design of near-space vehicles and its complex flight environment, there are many difficulties in the simulation research of control methods for near-space vehicles.
