  • Abstract
    The robust optimal control of linear uncertain systems with L 2-bounded uncertainties is addressed. The optimal state feedback control law in the so-called worst disturbance case is derived. The LQL method, minimax state estimation-maximin state feedback closed loop control scheme (LQL means linear quadratic L2-bounded uncertainties), is proposed. In a sense, the LQL method uses the idea of the linear-quadratic-Gaussian (LQG) method to treat H∞-optimizing design problems
