This note presents a design method for missile systems with linear time-invariant autopilot systems and propor tional navigation guidance(PNG) laws. In the design of missile control systems, the nonlinear planar pursuit situ ation is fully considered and using the well-known small gain theorem, a sufficient condition is obtained which guar antees a desired final miss distance and L2 stability of the closed-loop system. H∞ and LMI approach are employed to design a linear missile control system satisfying the gen erated sufficient condition.
