Abstract:For the problem of maneuvering aircraft in mall range high frequency lateral maneuvering flight, combined with the kinematics and dynamics equations, it gives the maneuvering amplitude and the maximum maneuvering frequency under the maximum available overload by the analytical method, and the optimal frequency of guidance law optimized by using the PSO method. Based on the analytic programming algorithm, it provides an analytical form of the sine maneuver guidance law to realize the maneuvering guidance flight of the aircraft in the lateral direction. The simulation results show that the analytical algorithm can precisely calculate the guidance law frequency, and the accuracy error of particle swarm optimization method is less than 5%. The sinusoidal maneuver guidance law can accomplish the mission target better at high speed. At a small speed, the amplitude error will increase slightly.
