ADRC BASED INTEGRATED GUIDANCE AND CONTROL SCHEME

Based on the active disturbance rejection control (ADRC), an integrated guidance and control scheme is developed for the pursuit of maneuvering targets. The ADRC based guidance law takes into account the nonlinearities and uncertainties involved both in the target kinematics and pursuer dynamics such that it can produce the guidance law which can zero the line-of-sight (LOS) rate even when the target is maneuvering. The ADRC based control law takes into account the nonlinearities and uncertainties existing in the motion dynamics such that the acceleration needed can be achieved. Furthermore, the capability of the proposed scheme is analyzed and the feasibility is tested by some simulations.
