Comparison analysis between fuzzy and fuzzified-PID methods on gun-barrel motion control

Cannon guns of 57mm-caliber are some of the main weapons owned by the air defense artillery divisions of Indonesian army. However, some of them still have to be operated manually to provide the direction course of the projectile following the target to be fired. This article presents the comparison of two possible control methods being implementable on the anti-aircraft cannonry system. The first one is the use of fuzzy-logic control method, whereas the second one is the integration of the fuzzy-logic algorithm into the commonly known proportional-integral-derivative control method. The control is aimed to direct the gun barrel toward the desired direction, in terms of both the azimuth and elevation angles based on the target position. The results show fuzzified-PID control method excels the fuzzy-logic control method in terms of steady-state error performance and settling-time performance in general.
