Flight Control Law Design Methods and New Development

Flight control technology, especially flight control law, is one of the most important key technologies of aircraft, and has made great progress with the development of aircraft. From the traditional stability augmentation systems to the command and stability augmentation system according to the requirements of the pilot, from the traditional pole placement method to the modern dynamic inversion control method, all of them reflect the application of control technology in engineering. Based on the development in flight control law design, this paper mainly focuses on design method dimension, and proposed the CSAS (command and stability augmentation system) control law based on the existing aircraft model. Then, the application of modern control theory in flight control law is discussed, and the design of CSAS control law is carried out by using the dynamic inversion method. Finally, the development trend of flight control law design is briefly predicted.
