Abstract
Systems with unknown nonlinear characteristics and unknown disturbances are linearized using dynamic feedback linearization based on linear extended state observer. Also a method for the parameter regulation is presented. And then for a given performance index, an optimal control law is designed using LQR theory. Finally numerical simulation results demonstrate that this control method can meet the performance requirement with good robustness.
