Abstract:

The impact angle control over guidance (IACG) law against stationary targets is proposed by using feedback linearization control (FLC) and finite time control (FTC). First, this paper transforms the kinematics equation of guidance systems into the feedbackable linearization model, in which the guidance law is obtained without considering the impact angle via FLC. For the purpose of the line of sight (LOS) angle and its rate converging to the desired values, the second-order LOS angle is considered as a double-integral system. Then, this paper utilizes FTC to design a controller which can guarantee the states of the double-integral system converging to the desired values. Numerical simulation illustrates the performance of the IACG, in contrast to the existing guidance law.

Key words: guidance law, impact angle, feedback linearization, finite time control, global stabilization
