Abstract

It is important to solve aircraft equilibrium point for flight control law design and performance analyses. According to the characteristic of aircraft general straight flight, a solution to the aircraft trim problem was proposed by using genetic algorithms. First, the equilibrium equations were set up from aircraft six degree of freedom nonlinear equations. Then based on the equilibrium equations, the fitness functions were built by using dynamitic function, state variable, and output variable. And then the equilibrium equations were resolved by applying genetic algorithms. Finally, an example of trim algorithm was used with a simulation by an aircraft.
