Abstract:	A mixed H(2)/H(∞) optimal control design and its application to a missile guidance problem of homing phase are studied. The problem consists of combining the performance requirements of quadratic optimal controllers with the robustness properties of H(2) controllers. Our approach has five features. (l)The complete nonlinear kinematics of the pursuit-evasion motion is considered; neither linearization nor small angle assumption is made here. (2) The nonlinear H(2)/H(∞) guidance law is derived analytically and express in a very simple form; neither iterative approximation nor complicated numerical computation is required. (3) Unlike adaptive and neural guidance laws, the implement of the proposed robust H(2)/H(∞) guidance law does not need the information of target acceleration. (4) Under appropriate constraints, the pair of cross-coupled Hamilton-Jacobi Partial Inequality (HJPDI) can be solved easily. (5) The derived nonlinear H(2)/H(∞) guidance law exhibits string robustness and excellent performance against intelligent adversary aircrafts.
