Description

technical field [0001] The invention relates to a semi-physical simulation platform and simulation method of a vertical take-off and landing vehicle based on labwindows+RTX, and belongs to the technical field of vehicle simulation. Background technique [0002] The existing vehicle simulation platform technology can achieve high simulation accuracy, but it requires multiple devices to work at the same time, which are used for dynamics calculation, steering gear control, communication, etc. Due to the large number of devices, clock ambiguity needs to be specially resolved question. This requires more equipment, high overhead, and reduced reliability. [0003] Therefore, it is an urgently needed technology to rationally arrange and simultaneously perform steering gear control, communication, dynamics calculation and other work on a computer to improve computer utilization, ensure reliability, and reduce overhead. Contents of the invention [0004] In order to solve the pro...
