Modeling and Simulation of Helicopter Swashplate Collective Control Response in UAV Applications

Unmanned Aerial Vehicles (UAVs), particularly quadcopters and rotorcraft, have become indispensable in various sectors due to their versatility and capability in tasks ranging from surveillance to payload transport. This paper presents a mathematical model for simulating the collective control of a helicopter's swashplate mechanism, crucial for optimizing rotorcraft UAV performance. The model integrates a flybarless swashplate system with a high-performance brushless DC motor and servo actuators, implemented and analyzed using MATLAB Simulink. By developing and testing control responses through PID tuning, the study aims to enhance the maneuverability and efficiency of rotorcraft UAVs. The key findings suggest that adjusting rotor speed provides a more responsive control method than traditional blade pitch adjustments, highlighting the benefits of high-power BLDC motors. The results provide valuable insights into improving UAV flight precision and operational effectiveness, addressing gaps in existing research and contributing to the advancement of UAV technology.
