Popis:	A numerical difficulty arises when the existing nonlinear H/sub /spl infin// control formulas are employed to solve the H/sub /spl infin// I/O (input-output) linearization problem, which is formulated as an output feedback nonlinear H/sub /spl infin// control problem. We propose a modified nonlinear H/sub /spl infin// controller and successfully remove the numerical difficulty. A successive algorithm is also given to solve the Hamilton-Jacobi equation which is essential in the solution of the nonlinear H/sub /spl infin// control problem.
