An analytical review on FPGA based autonomous flight control system for small UAVs

Recently small UAVs are widely used in real world applications. In the absence of the pilot, Flight control system (FCS) is the brain of the any aircraft especially in the UAVs. FCS can use various controllers such as conventional PID Controller, combination of PID controller with Kalman filter, fuzzy logic controller and FPGA /DSP based controller, etc. This paper presents, brief explanation of four techniques used in the development of the flight control system for small UAVs namely, purpose of work, flow diagram, advantages and disadvantages. Field Programmable Gate Array (FPGA) /DSP based small UAVs are better one, as it is a low power, fast response, less volume and compatibility to applications. The aim of this paper is to achieve a suitable characteristics compatible with applications in the field of unmanned aviation.
