Unmanned aerial vehicle semi-physical simulation system

Abstract

The invention discloses an unmanned aerial vehicle semi-physical simulation system, which comprises a test management system, a simulation calculation system, an IO simulation system, a signal conditioning unit, a signal disconnection system, a fault injection system and a flight control machine object, and is matched with a semi-physical simulation system for resolving an environment in real time. The excitation signal of a tested object can be closer to the electrical signal of the real operation environment, and the feedback signal of the tested object can be obtained in time, so that the semi-physical simulation test is closer to the real test environment; an airborne equipment model is isolated from an IO scheduling model calculation environment, so that the operation resource of an airborne equipment mathematical model can be isolated from an equipment IO scheduling resource, and the calculation real-time performance of a dynamic model and the airborne equipment model is more powerfully guaranteed; and a signal conditioning and disconnecting device increases expandability and universality for the semi-physical simulation system, and the fault injection device provides environment support for a fault tolerance test of a tested object in a simulation test.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle simulation, and relates to a semi-physical simulation system for an unmanned aerial vehicle. Background technique [0002] As the control center and control algorithm operation system of the UAV, the flight control computer mainly completes the functions of flight state management and control command resolution. Due to its unmanned nature, there are higher performance requirements in terms of remote communication and control algorithm reliability and stability. The verification test of the flight control computer becomes an important part of the UAV reliability test.
