- Abstract
This study presents a guidance law to intercept non‐manoeuvring targets at a desired impact angle. The desired impact angle, defined in terms of a desired line‐of‐sight angle, is achieved by selecting the missile's lateral acceleration to enforce the sliding mode on a sliding surface. Then, the authors use the Lyapunov stability theory to prove the stability of the proposed non‐linear sliding surface. Furthermore, they introduce the adaptive neuro‐fuzzy inference system (ANFIS) to adaptively update the additional control command and reduce the high‐frequency chattering of sliding mode control (SMC). The proposed guidance law, denoted ANFSMC guidance law with impact angle constraint, combines the SMC methodology with ANFIS to enhance the robustness and reduce the chattering of the system. The effectiveness of the ANFSMC guidance law is also verified by the numerical simulations.
