The embodiment of the invention discloses a semi-physical simulation method and system. The method comprises the steps that a simulation module carries out simulation calculation, and generates missile motion information, a microwave array control instruction and a three-axis turntable control instruction; a sight line information acquisition module generates relative sight line information according to the angle information of the microwave array; a motion information acquisition module generates missile motion information according to the angular motion of the three-axis turntable; an information recombination module collects the missile motion information output by the simulation module and the motion information acquisition module and carries out online processing on the missile motioninformation according to simulation time; and a guidance control module collects the missile motion information of the information recombination module and the relative sight line information of thesight line information acquisition module so as to complete guidance control. The online recombination semi-physical simulation test based on the motion information is accurately completed with a highreduction degree.
Description
technical field [0001] The embodiments of the present application relate to the technical field of simulation, and in particular to a half-physical simulation method and system. Background technique [0002] The semi-physical simulation test is a test that connects the controller and the control object simulation model realized on the computer. It can truly reflect the dynamic characteristics, static characteristics and nonlinear factors of the controller. It is a A closer to the actual test. [0003] During the hardware-in-the-loop simulation test, the three-axis turntable provides an angular motion environment for the inertial measurement unit (hereinafter referred to as the inertial measurement unit) and the seeker installed on it, and the microwave array provides relative line-of-sight information for the seeker. According to the traditional hardware-in-the-loop simulation method, for a ballistic with a large angular motion span, the angular simulation range of the micr...
