In this paper, the design of nonlinear H/sub /spl infin// controller for autopilot application is presented. The design of nonlinear H/sub /spl infin// control action leads to a partial differential inequality or equation, namely, Hamilton-Jacobi-Isaacs (HJI) inequality. It is too difficult, if not impossible, to find an exact closed form solution for this inequality. However, there are some approximate solutions. In this paper, we will make use of one of the most efficient possible methods, Taylor Series Expansion of nonlinear terms appear in HJI. Simulation results of the proposed method on a missile's autopilot design show the effectiveness of the proposed algorithm.
