Abstract :
A successive approximation solution approach is used to solve the Hamilton-Jacobi-Isaacs partial differential Riccati equation that arises in nonlinear H∞ optimal control problems. The method of characteristics is used to form integral expressions used to solve the partial differential Riccati equation. Successive approximations are then used to approximate the solution to these integral expressions. Two examples in which the optimal control is known are presented. These examples outline the approximate solution approach and provide insight into what degree of approximation is needed
