METHOD OF PARAMETER OPTIMIZATION FOR ENSURING LONGITUDINAL AXIS STABILITY AND FLYING QUALITY FOR AIRCRAFT

摘要

The present invention is to design a target dynamics configured to remove dynamic characteristics of an aircraft and to calculate a dynamic demand input, and calculate a mathematical nonlinear model of an aircraft by inputting the difference between the angular acceleration measured from the angular acceleration sensor and the dynamic demand input as input. It relates to a parameter optimization method for satisfying the stability and flightability of the vertical axis of the aircraft, including the step of optimizing the parameters of the controller of the target dynamics and designing an inverse motion model represented by angular acceleration by removing it with (Inversion). The parameter optimization method for satisfying the stability and flightability of the vertical axis of the aircraft according to the present invention can satisfy the flightability margin based on the incremental dynamic reverse conversion control method using the angular acceleration sensor, and improve the phase margin and equivalent time delay characteristics It has the effect of satisfying the stability at the same time, making it easy to obtain airworthiness certification.
