Abstract

The invention relates to an aircraft simulation electric load control system based on a heterogeneous computing structure of an embedded CPU and an FPGA. Based on a controller of an embedded CPU and reconfigurable FPGA architecture, different I / O function modules are configured according to requirements, an airplane simulation point load power calculation and adjustment system platform is built, the system performance is improved, and the design of an embedded control and monitoring system is simplified. Functions respectively realized by software and hardware are reasonably divided, and dataacquisition and control logic are realized by fully utilizing the rapidity and stability of complete reconfiguration and hardware timing of the FPGA; and the advantage that the embedded CPU can complete complex algorithm calculation is fully utilized to realize a difference matching algorithm and a good interaction interface.

Description

technical field [0001] The invention relates to the technical field of simulated electrical loads for aircraft finalized flight tests, and relates to an aircraft simulated electrical load control system based on a heterogeneous computing structure of an embedded CPU and FPGA. Background technique [0002] In the field of simulating electrical loads in aircraft flight test subjects, it is necessary to design a complete system to achieve a specific state of the output power of the aircraft power system generator to meet the requirements of some flight test subjects. By controlling the resistance parameters of the variable load to match the power of the generator, and to ensure that the aircraft can interrupt the connection between the generator and the load after some functions of the system fail in an emergency, an emergency unloading mechanism needs to be designed. General civil aircraft often use industrial control computer as the core control system to realize automatic co...
