摘要: This paper presents a nonlinear parameter-varying modeling approach to duplicate the aircraft dynamic behavior while moving from one flight region another. starts by generating local two-term truncatedVolterra series, which is enough capture quadratic andbilinear nonlinearities, at different operating conditions over envelope. The variation of these series’ coefficient matrices are then sought through interpolation techniques. A F-16 longitudinal model was used assess proposed approach. improvement in accuracy predict, understand, and analyze previous linear approach, effectively ignored second-order stability control derivatives, demonstrated many numerical test cases.
