For Small Unmanned Aerial Vehicles (SUAV), because of its wide flight envelope and its own flight control system has many uncertainties, the aircraft itself is also vulnerable to strong interference such as atmospheric turbulence, so a robust controller is required to meet the specific performance requirements. In this work, a H∞ algorithm, based on a Linear Matrix Inequality (LMI), is used to the design of multivariable flight control system for the longitudinal motion mathematical model of a SUAV in a key laboratory. The simulation result demonstrated that the control system cannot only guarantee the stability of the closed-loop, but also has good robustness for internal and external disturbances.
