Control Strategies and Novel Techniques for Autonomous Rotorcraft Unmanned Aerial Vehicles: A Review

摘要: This paper presents a review of the various control strategies that have been conducted to address and resolve several challenges for particular category unmanned aerial vehicles (UAVs), emphasis which is on rotorcraft or rotary-wing systems. Initially, brief overview important relevant definitions, configurations, components, advantages/disadvantages, applications UAVs first introduced in general, encompassing wide spectrum flying machines. Subsequently, focus more two most common versatile UAVs, namely, twin-rotor quadrotor Starting with background dual-rotor helicopter quadcopter, full detailed mathematical dynamic model each system derived based Euler–Lagrange Newton-Euler methods, considering number assumptions considerations. Then, state-of-the-art diverse controlling systems conceivable solutions when are subjected different impediments demonstrated. To counter some these limitations adverse operating/loading conditions innovative techniques particularly highlighted, their performance duly analyzed, discussed, compared. The applied deemed produce useful contribution successful implementation wake varied constraints demanding environments result degree robustness efficacy. Some off-the-shelf developments research commercial also presented.
