Aeroengine Nc Simulation System Software Design

Result from the developing of aero-propulsion technology and multi-variable control technology, extra high control precision is demanded. In order to meet the demand, aero-engine control system becomes more and more complicated, hydraulic system that used widely in the past is hard to or cannot achieve that precision. The digital electronic controller characters with high running speed, high precision, flexibility in designing etc, it overwhelms the other design method in aero-engine controller design.What the paper discusses is part of aero-engine real-time digital electronic control simulation system. Through analyzing the requirement in technology and functions of the system, this paper presents techniques to build the system. The paper focuses on software designing, including simulating digital controller, communicating between computers and computer with other devices, and graphics interface with user and interfaces with hardware. The project can meet the requirement for engineering application through primary testing.
