The nonlinear relative dynamics between the interceptor and the target in the vertical plane is analyzed with the target acceleration being viewed as an unknown disturbance. By defining the sliding surface as the input variable of fuzzy rules, the adaptive laws on a Lyapunov function are developed to adjust the parameters of the fuzzy rules to guarantee the stability of the system. The guidance law not only keeps the line-of-sight rate between interception and target converging to zero, but also guarantees intercepting all kinds of maneuvering targets.
