Missile Guidance Law Design Using Nonlinear Output Regulation and T-S Model

The design of missile guidance law based on output regulation theory and Takagi Sugeno fuzzy model have been studied. In this design, the guidance problem is converted to the nonlinear regulator problem. The three-dimensional command to line-of-sight guidance problem is formulated as a tracking problem of a time-varying nonlinear system. It is provided the solution in terms linear matrix inequalities allowing the use of numeric techniques in the search of a guidance controller. Simulation results for different engagement scenarios illustrate the validity of the proposed guidance law.
