The Design of Optimal Fuzzy Guidance Law with Terminal Constraints

This paper studies the optimal fuzzy guidance law for intercepting arbitrarily maneuvering evader with the terminal constraints. The interception nonlinear model is approximated by the fuzzy T-S linear model. A new fuzzy and robust guidance law is obtained by using the receding horizon control strategy and adjoint technique. That the evader maneuvers in small scope can be tackled with the corresponding fuzzy linear model. And that the evader maneuvers in large scope can be treated with the model-switching among a series of linear model. This guidance law is easy to be implemented. The simulated result connotes that the guidance law can intercept arbitrarily maneuvering evader precisely.
