Problems solved by technology

[0007] The present invention is realized in this way, and solves the technical problems: (1) The simulation of the current aircraft power supply system is mainly based on pure software simulation, and most of them fail to consider the influence of the load model on the aircraft power supply system well, which just cannot be done well. It reflects the influence of complex electrical load characteristics on modern large aircraft on the quality of aircraft power supply; (2) The excitation control algorithm of the aircraft power system is basically based on traditional PID, even some advanced algorithms are complex and reliable due to the complexity of the algorithm itself. Due to reasons such as the fact that the security verification has not reached a good level, it cannot be used in practice for the time being.

Embodiment Construction

[0022] In order to reduce the complexity of aircraft power system simulation development, improve its domain-based reuse, and make the system meet the requirements of openness, integration, distribution and versatility, a virtual simulation system of aircraft power system based on multi-AGENT technology is adopted. Structure, and use AUML (Agent Unified Modeling Language) to organically integrate the analysis, design and implementation of the entire system. The architecture provides theoretical guidance and method basis for building aircraft power system standardization platform and developing practical application system.

Abstract

A semi-physical simulation method of an aircraft electric system based on an AGENT modeling technique comprises a method for a virtual operating environment modeling method of intelligent control and test of an aircraft power system, a method for setup of a simulation model of a modern aircraft power system based on a multi-AGENT technique, a method for knowledge base modeling supporting decision assessment, a method for achievement of a semi-physical simulation platform, and a performance assessment method of the aircraft electric system. The method fully embodies a complete simulation model of distributed power control of a modern large aircraft, overcomes disadvantages that the aircraft power system is simulated mainly based on pure software at present and the effect of a load model on the aircraft power system cannot be well considered mostly; on the basis of setting up the model of the aircraft electric system based on the AGENT technique, with the adoption of a high-speed data collecting card, the method can conveniently form an effective semi-physical simulation verification platform together with a voltage regulator of an aircraft power generator and related detecting devices to verify reliability and safety of excitation control of the large aircraft electric system in real time.

Description

technical field [0001] The invention relates to a semi-physical simulation method for an aircraft power system based on the AGENT modeling technology. Background technique [0002] The aircraft power system consists of a power supply system and a power distribution system. Its function is to provide electrical energy to all electrical equipment on the aircraft (such as flight control system, avionics system, fire control system, etc.) to ensure the safe flight of the aircraft and complete transportation. and combat missions. With the rapid development of large aircraft in the direction of multi-electricity and full-electricity, the structure and control of modern aircraft power systems are becoming more and more complex, various electronic devices on the aircraft are increasing, the power consumption is increasing, and the characteristics of the power load are also increasing. In addition to conventional linear loads, there are a large number of non-linear loads such as con...
