Problems solved by technology

[0005] However, this method also has the following obvious deficiencies: First, the rapid prototyping simulation method of the aero-engine control system fails to realize dual-channel simulation, so the dual-channel control and algorithm cannot be simulated; A single user is allowed to operate, and multiple users cannot work at the same time; the third is that the simulation method needs to use at least two hardware devices, which takes up more resources
