An evaluation method for a fight control law based on modified differential evolution (DE) algorithm is provided. A new modified method based on chaos theory (CT) and Gaussian disturbance (GD) is proposed to deal with the problem of slow search and premature convergence in the basic DE algorithm. Compared with the basic DE and other DE methods, experimental simulations show that the proposed method can not only significantly speed up the convergence, but also effectively solve the premature problem. And then the process to proceed the evaluation of the flight control law is put forward. Finally, the new method is applied to the evaluation of a flight control law. Result shows that the new method overcomes the limitations of the traditional evolution method, and can achieve satisfied results both for the whole flight envelope and for all predictable parameter perturbations.
