| Summary: | <p align="justify">Cruise missiles are one type of unmanned weapon used to attack a long-range <br />
<br />
target with a precise angle of impact. The flight in the cruise phase is carried out <br />
<br />
at low altitudes with the terrain following guidance system. In the terminal phase, <br />
<br />
the missile aims a specific point on the target. The cruise phase guidance system is <br />
<br />
supported by a stabilization system and a normal acceleration and an altitude <br />
<br />
tracking system. The guidance system for terminal phase is supported by the same <br />
<br />
tracking system but without altitude tracking system. <br />
<br />
The guidance and control systems design is carried out in stages. The terrain <br />
<br />
following system works with 2 algorithms, i.e. weighting equation and moving <br />
<br />
average, to produce guides in the form of flying heights. The impact angle guidance <br />
<br />
system works with proportional navigation guidance law. Control gains of the <br />
<br />
stability augmentation system are designed using linear quadratic regulator <br />
<br />
method. The control augmentation system gains are designed using a PID <br />
<br />
controller. <br />
<br />
The missile that have been equipped with guidance and control systemsis tested in <br />
<br />
cases. The case in cruise phase is done by the missile facing 2 types of obstacles. <br />
<br />
Flight in the terminal phase tested to impact the target from 2 directions. The results <br />
<br />
of the cruise phase test show that the missile can pass the obstacle properly if the <br />
<br />
obstacle characteristics fulfill the maneuver restrictions. Meanwhile, the test <br />
<br />
results in the terminal phase indicate that missile maneuvers is not fast enough to <br />
<br />
follow the guidance, resulting in miss distances. Several methods to restore the <br />
<br />
problem are proposed.<p align="justify"> |
