Development of a Stabilizing Adaptive Feedback Control System for Helicopter Gun Turrets

Abstract

This study introduces a stabilizing controller design for a helicopter gun turret system using an adaptive backstepping control approach. To model the gun turret system, a two-degree-offreedom manipulator dynamics is employed, which enables precise control over the weapon pointing mechanism. The proposed controller design utilizes an adaptive backstepping control strategy to ensure system stability and robustness against disturbances such as firing and other operational conditions. Additionally, the design includes an advanced feedback mechanism that dynamically adjusts to changes in the helicopter's flight dynamics, further enhancing control accuracy. Simulation results show the efficacy of the controller, achieving stable and precise control of the gun turret system. The study offers a simplified model to enhance the performance of helicopter gun turret systems, with potential applications in military ground and naval vehicles. The proposed controller design is a promising solution to improve the precision and stability of the gun turret system, contributing to safer and more efficient defense systems.
