Nonlinear robust digital controller based on fuzzy model for homing missiles

This paper utilizes Takagi and Sugeno’s fuzzy model to approximate the nonlinear homing missile–target dynamics. On the basis of Takagi and Sugeno’s fuzzy model we construct a robust digital controller to handle the missile for intercepting the unpredictable maneuvering target. The derived stability conditions are also proposed to support the stability of the digital closed-loop systems. An example is given to demonstrate the efficiency of the proposed missile digital controller.
