Research on Semi-physical Real-time Simulation Technology of Unmanned Helicopter Based on Linearized Model Group
Aiming at the difficulty of modeling and low confidence of the nonlinear dynamic model of unmanned helicopter,which is not conducive to affecting system simulation and verification.First,the lin-earization model group of unmanned helicopter is introduced and the linearization of nonlinear model is studied;then,the real-time simulation algorithm and calculation process based on linearized model group are described;finally,the semi-physical simulation environment based on the linearized model group is de-signed,and the real-time simulation software,simulation monitoring software and FlightGear communica-tion design are completed and verified by simulation.The results show that the semi-physical real-time simulation system based on the linearized model group can well meet the engineering requirements and a-chieve the expected research objectives.
