Three-Axis Control and Position Control for Optimal Control of 3-DOF Helicopter

In the control of a 3-degree-of-freedom helicopter system, both three-axis control and position control must be addressed. Consequently, when implementing optimal control strategies, thorough research and analysis of these two aspects are essential. For three-axis control, precise control strategies for pitch, roll, and yaw axes must be established to maintain stable aerial stabilization - typically implemented through PID controllers or modern control algorithms like LQR that adjust rotor speeds based on inertial sensor feedback. Position control requires comprehensive consideration of the helicopter's spatial coordinates and orientation, involving coordinate transformation calculations and trajectory tracking algorithms such as waypoint navigation or model predictive control. The original program requires modifications and enhancements - potentially through state-space modeling, gain scheduling optimization, or integration of sensor fusion techniques - to better achieve optimal control performance for the 3-DOF helicopter system.
