A Novel Disturbance Rejection Control of Roll Channel for Small Air-to-Surface Missiles

In this paper, the issue of roll channel for attitude control small air-to-surface missiles suffering from multiple disturbances is investigated. The dynamic model established and controller based on active disturbance rejection (ADRC) designed. Based extended state observer, observed compensated to track rate accurately. Then, simulations verification are carried out rudder efficiency, barycenter location deviation, steering gear stuck, wind disturbance, drift error inertial measurement unit (IMU) other disturbances. effect also compared with proportional integral derivative (PID) ADRC algorithms. results demonstrate that algorithm has a good ability suppress It can meet performance requirements missiles.
