摘　　要：针对防空火箭炮运行时负载与参数大范围变化的特点,结合递阶控制理论,设计一种两层改进型递阶控制策略。其中,决策级根据火箭炮的运行状态计算实时转动惯量,实时控制级采用二阶滑模控制器,能在满足系统指标的前提下平滑控制输入曲线、有效抑制系统参数摄动与外部干扰。计算机仿真和实验表明,使用该控制策略,系统具有较好的鲁棒性与动态响应性能。An improved 2-level hierarchical control strategy was designed to overcome parameter pertur- bation 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 var- iations and external load disturbances. Both simulation and experiment show that this strategy can guaran- tee the dynamic performance of system and has strong robustness.
