Abstract: Some issues in adaptive control of generic aircraft with asymmetric damage and its key conditions were analyzed.A thorough study of modeling, linearized aircraft models and coupling of lateral and longitudinal dynamic was presented. And the detailed proof of the key condition for model reference adaptive control(MRAC): the invariance of the signs of principal minors of the high frequency matrix and the infinite zero structure was performed which demonstrates the theoretical feasibility of MRAC of generic aircraft with asymmetric damage. At last, simulation results were given to illustrate the design and performance of adaptive control systems for aircraft flight control. -
