Abstract: An improved 2-level hierarchical control strategy was designed to overcome parameter perturbation and load disturbance in antiaircraft rocket launcher systems. Its decision-making level was used to calculate the moment of inertia according to the system status, and a novel 2-order sliding mode controller was adopted in the real-time control level to smooth the control input curve and restrain the parameter variations and external load disturbances. Both simulation and experiment show that this strategy can guarantee the dynamic performance of system and has strong robustness.

Key words: automatic control technology, armament launch theory, antiaircraft rocket launcher, hierarchical control, 2-order sliding mode
