Integrated design of missile guidance and control: Active disturbance rejection control method

In this paper, we present an active disturbance rejection control (ADRC) based integrated guidance and control (IGC) law. The IGC law is designed using the backstepping technique, and the particle swarm optimization (PSO) algorithm is utilized to find the optimal selection of the controller parameters. Simulation results show that, with the application of the proposed IGC law, small miss distance can be achieved, and the system is robust against target maneuver and system uncertainties.
