Modeling control and simulation of two axes gimbal seeker using fuzzy PID controller

TLDR: In this article, the authors presented the model of two-axis gimbal seeker and improved its performance using proposed fuzzy controller The equations of gimbals motion are derived using Lagrange equation and the stabilization system is constructed considering the missile rates, torque disturbances, and cross coupling between elevation and azimuth channels The overall control system is simulated using MATLAB/Simulink This model is evaluated comparing with conventional PI control system

Abstract: The application of the guided missile seeker is to provide stability to the sensor by isolating it from the missile motion and vibration The aim of this paper is to present the model of two axes gimbal seeker and improve its performance using proposed fuzzy controller The equations of gimbals motion are derived using Lagrange equation and the stabilization system is constructed considering the missile rates, torque disturbances, and cross coupling between elevation and azimuth channels The overall control system is simulated using MATLAB/Simulink This model is evaluated comparing with conventional PI control system The comparative simulation results in different conditions have shown that the proposed fuzzy PID method offers a better performance than the classical one
