An FL-PID Mixed Technique to Control a Military Rocket Launcher System Board

Abstract

This article proposes the design and construction of an automatic launcher system for military weaponry. Combining the fuzzy-logic and proportional-integraldifferential control theories, the launcher system board is purposed to automatically direct a military rocket along its azimuth and elevation angles direction. The fuzzy-logic method has been explored to find the values of Kp, Ki and Kd constants of a proportional-integral-differential controller, which will then be used to adjust the angular position of actuator according to a predetermined set-point. The combined control algorithm has been implanted on the Arduino Mega 2560 and implemented to launch the 70 mm-caliber Rolex rocket being considered during the experiment. Successful control result, which was indicated with the average steady-state error value of 0%, has been resulted.
