Model-Free Control Design Using Incremental Approximate Dynamic Programming and Generalized Extended State Observer

A model-free control strategy is proposed which minimizes the cost function consisting of decision and ob-servation. Real-time control can be achieved for unknown systems without relying on any pre-trained policies and model information. By estimating various external disturbances and model uncertainties to stably achieve the control goal, robust-ness can be improved. The numerical simulations demonstrate the effectiveness of the proposed method in controlling the acceleration of missiles.
