Comprehensive review of various control strategies for quadrotor unmanned aerial vehicles

The Quadrotor Unmanned Aerial Vehicles (UAVs) have gained significant attention in recent years due to their versatile applications civilian and military sectors. It is a highly nonlinear underactuated system an outdoor flight; it always subjected external disturbances wind gusts other environmental factors. Implementing the control strategies could be improved terms of high computational time, uncertainty, approximation error, large amount training data. One major challenges development quadrotors design efficient reliable system. This paper presents comprehensive review various for evaluates performance. includes classical techniques such as PID (Proportional-Integral-Derivative) LQR (Linear Quadratic Regulator) modern adaptive fuzzy control. Comparative analysis has been presented with key future directions. study provides useful guide researchers engineers systems quadrotors.
