Study on Trajectory Tracking Guidance Method for Spin Stabilized Projectile Based on Velocity Direction Correction
摘要
Abstract
A trajectory tracking guidance method based on velocity direction correction was proposed for the design of guidance law of spin stabilized 2D trajectory correction projectile(TCP). The laws of attack angle motion and velocity motion while the fixed canards generated step excitation were derived,and the relationships between the phase angle of average deflection angle and the roll angle of fixed canards were obtained. By generating a virtual future point on the standard trajectory, the commands of the velocity angles were obtained. The principle was proposed by correcting errors between the velocity direction and the commands,and the tracking of standard trajectory was achieved. A new standard trajectory can be generated in real time through the impact point prediction while the actual trajectory is far away from the standard trajectory. The simulation results show that,when the firing angle is small,the velocity direction correction can be used to track the standard trajectory on the whole trajectory. When the firing angle is large, the standard trajectory can be generated on downward phase, and then the velocity direction correction can be used to track the new standard trajectory.关键词
