FLIGHT DYNAMIC ANALYSIS MODELING DEVICE FOR HELICOPTER FBW SYSTEM AND CONTROLLING METHOD FOR THE SAME

摘要

The present invention provides a flight dynamics modeling device for a helicopter FBW system and a control method thereof. The flight dynamics modeling device for a helicopter FBW system includes: a sub system module which consists of a plurality of block models to model devices each provided in a variety of helicopter modules; a control module which controls a process of analyzing and modeling a flight dynamics process through each block model formed in the sub system module, and controls modeling of a helicopter suitable for a development environment using a preset batch process; a trim analysis routine module which evaluates the flight performance of each block model formed in the sub system model and initializes a temporal area simulation, according to function control signals from the control module; a stability analysis routine module which conducts linearization and determines stability through an eigenvalue value, according to the function control signals from the control module; and a simulation routine module which evaluates a control law and determines whether the performance meets the flight control stability of ADS-33, according to the function control signals from the control module. The present invention as described above can model sub systems of a helicopter through a separate module and can construct an efficient interface suitable for a development environment using a batch process to design the helicopter while quickly modifying or changing the development task of the helicopter according to the development requirements, thereby shortening a development cycle and rapidly processing a check of performance.
