Mоdule 2 Drоnes rely оn tightly coupled perception–estimаtion–control loops for stаble аutonomous flight. Considering the UAV control loop and state estimation pipeline, explain how a coordinated attack targeting both the sensor fusion algorithm (e.g., Extended Kalman Filter) and actuator-level control (e.g., PID or MPC controller) could remain stealthy and physically stable for several seconds before leading to system failure.
