Efficient control technology for antenna testing system based on UAV platform
In order to obtain the beam shape and parameters of phased array antennas in different working en-vironments,it is necessary to install a micro-receiver on the drone,which accurately controls the spatial position of the drone and measures its received power.Due to gust interference during the use of drones in the outfield,it is difficult to accurately control the position and attitude of the drone.A robust controller based on PID+LQR al-gorithm for the inner and outer loops is studied and applied to a quadcopter drone.The simulation analysis of the overshoot and time response result of the controller shows that under wind disturbance conditions below level 6,the controller can effectively control the position and attitude of the quadcopter drone,which meets the require-ments of phased array antenna parameter measurement.
