  Abstract

This paper proposes a novel differential Evolution algorithm, Zone-Focused Differential Evolution (ZFDE), to enhance the attitude control performance of Unmanned Aerial Vehicles (UAVs) by efficiently optimizing the gains (Kp, Ki, Kd) of PID controllers. In real-time control systems such as UAVs, computational efficiency and fast convergence are of paramount importance. However, the conventional Differential Evolution (DE) algorithm, which performs operations over the entire population, can lead to high computational costs and low search concentration. To address these issues, the proposed ZFDE generates a large initial population and then filters out only the top N of individuals based on cost values to form a fixed search group for all subsequent DE operations. This approach enhances search focus while reducing redundant computation, thereby providing a more suitable optimization structure for realtime UAV PID tuning. Simulation experiments conducted in MATLABdemonstrate that the proposed ZFDE algorithm outperforms conventional DE in terms of stable convergence to the best cost and reduced computational load. These results suggest that ZFDE is a promising optimization strategy for real-time control environments such as UAV systems.
