A survey of control algorithms for Quadrotor Unmanned Helicopter

Basic structure of Quadrotor Unmanned Helicopter (QUH) and its practical application values are introduced as well as several control algorithms, such as, intelligent PID algorithm, linear quadratic LQR algorithm, H∞ loop-shaping algorithm, sliding mode control algorithm, feedback linearization control algorithm, adaptive control algorithm and backstepping design algorithm and then analyses merits and drawbacks of above control algorithms. At last, our research prospects the major research aspects and development direction on future researches of QUH.
