摘要

Abstract

UAVs carrying liquids are subjected to imbalance caused by liquid shaking during flight

which leads to shaking of the UAV itself

especially when braking sharply. While most of the existing studies at home and abroad focus on the structural optimisation of the tank itself

such as adding damping

and most of the research into wobble generation is wind force very few optimise the shaking caused by the liquid by means of a controller. In this paper

we study to reduce the shaking of UAV based on PID control

which can reduce the structural complexity of the water tank and lower the cost. In this paper

we first establish the mathematical equations of UAV dynamics and the equations of liquid-carrying UAV dynamics

and build their Simulink models to regulate their motion by PID. The study shows that the effect caused by liquid shaking is not negligible

and the model in this paper can well optimise this shaking and pave the way for future research on UAVs carrying more dynamic objects.
