PD_PI Fuzzy Controller Based on PSO for Stabilization of Single-Axis Gimbal System

Nowadays, the gimbal stabilizes the line of sight and eliminates vibration in systems such as imaging, radar line of sight, and position stabilizers. The gimbal system tries to maintain the system's current state by dealing with the changes made in the system's current state. This system reduces unwanted motion disturbances and vibrations. The most common use of the gimbal system is in modern photography equipment. In this article, a single-axis gimbal stabilizer system that uses a PD_PI fuzzy controller has been investigated and the PSO algorithm has been used to optimize and calculate controller coefficients. The dynamic relations of the gimbal are described and the proposed control system based on the PD_PI fuzzy controller is optimized using the PSO algorithm. The controller coefficients have been optimized with the lowest possible settling time. The comparison of the obtained results shows that this controller has less settling time and much less overshoot than other controllers such as PID and fuzzy PID controllers.
