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

This paper is concerned with the design of missile guidance law based on robust output regulation theory and Takagi-Sugeno fuzzy model. In this design, the guidance problem is converted to the nonlinear regulator problem. The three-dimensional (3-D) command to line-of-sight (CLOS) guidance problem is formulated as a tracking problem of a time-varying nonlinear system. It is provided the solution in terms LMIs 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.
