Application of genetic algorithms in control law parameters identification

According to the problem that the design and adjustment of aircraft control law relies on experience to a great extent at present,applying with genetic algorithms,one method of parameter identification is put forward.First,design climb control law of a certain domestic aircraft.Then,construct suitable decoding formulas for unknown parameters of control law and set corresponding fitness function.Finally,basing on airborne prior flight data,by judging fitness function,calculate optimal unknown parameters.The imitation result shows that pitch angle and airspeed are stable,deviation value of cruising altitude is lower than 1.5%.The design method can get good control precision and meet practical needs.
