In this paper, a new nonlinear Hinfin control technique, called thetas-D Hinfin method, is employed to design a missile longitudinal autopilot. The thetas-D Hinfin design has the same structure as that of linear Hinfin, except that the two Riccati equations that are part of the solution process are state dependent. The thetas-D technique yields suboptimal solutions to nonlinear optimal control problems in the sense that it provides an approximate solution to the Hamilton-Jacobi-Bellman (HJB) equation. It is also shown that this method can be used to provide an approximate closed-form solution to the state dependent Riccati equation (SDRE) and consequently reduce the on-line computations associated with the nonlinear Hinfin implementation. A missile longitudinal autopilot design demonstrates the capabilities of thetas-D method. This new nonlinear Hinfin design also shows favorable results as compared with the linear H design based on the linearized model.
