Abstract�� Advanced agile missiles possess maneuverability, agility and accurate guidance performance by adopting thruster vector control or reaction control system thruster. System dynamics and modelling of the advanced agile missiles is investigated, a variable-structure model-following control approach for the agile missile with reaction control system thruster is presented, real-time logic switching control law is used. In order to overcome the chattering problem existing in most variable-structure control systems, simple fuzzy control laws are introduced in the variable-structure control system, which proved to be effective in not only chattering problem subduction bust also the system robustness enhanced. Numerical simulation results are given to illustrate the effectiveness.
Keywords�� thrust vector control   fuzzy control theory   robustness   agile missiles   variable-structure control
