With the widespread use of quadrotors in engineering practice, the requirements for their control systems’ performance such as accuracy, rapidity, adaptability are also enhanced. Digital twin as research focus in recent years can simulate the behavior of physical entities in the real environment by means of data and models. The operational efficiency of physical entities or systems can be improved by the precise digitization of physical objects. The digital twin technology is introduced into the control system of quadrotor, and the architecture of digital twin system of quadrotor is established. The related technologies involved in the implementation of the system are described in detail:How to model the digital twin system of quadrotor? How to use sensor technology and wireless communication technology to solve the data acquisition and transmission? And how to use Hadoop technology for big data storage and mining? Subsequently, model simulations and field tests are carried out on the actual quadrotor to verify the effectiveness of the system. The system can optimize the flight control and fuselage state by using the twin data and make the operation process of the quadrotors transparent.
