Abstract

Inertial / atmospheric data combined hardware-in-the-loop simulation system belongs to the technical field of aircraft navigation / control simulation, and is characterized in that it consists of a dynamics / kinematics simulation module, an inertial measurement component simulator, an angle of attack / sideslip angle simulator, an inertial / atmospheric data Combination filter computer and error real-time display / record module are composed of five parts. Through the real-time calculation of aircraft dynamics simulation computer, matching angular velocity signals and angle of attack / sideslip angle signals are generated as input to inertial / atmospheric data combination filter computer. The invention provides fast and low-cost simulation test means for the verification of the inertial / atmospheric data combined filter computer and its combined filter algorithm, and has the advantages of high test precision, convenient use and the like.

Description

Inertial / atmospheric data combined hardware-in-the-loop simulation system technical field The present invention relates to a kind of verification inertial navigation system and angle of attack / sideslip angle sensor combined filtering computer and its The invention relates to a hardware-in-the-loop simulation system of combined filtering algorithm, which belongs to the technical field of aircraft navigation / control simulation. Background technique Angle of attack and angle of sideslip are the important parameters that determine aircraft flight state, also are flight control and navigation system required The two important parameters, the tolerance deviation of the angle of attack will cause a large error in the calculation of the control law for the fighter, And it may cause the aircraft to be uncontrollable under a certain angle of attack. The angle of attack is also required by the aircraft flight control system and stall alarm An important parameter; the deviation ...
