摘要
针对全电坦克火炮稳定系统存在自身不确定性和外部干扰影响、行进间动态目标跟踪不易稳定的难点,设计一种自适应鲁棒控制器,从而满足新一代坦克高速行进间射击的性能指标。综合考虑了坦克行进间火炮稳定系统的非线性、耦合性和不确定性,基于伺服电机和电动缸动力学特性,建立了全电执行器的坦克双向稳定系统动力学模型,并将模型以状态空间形式表达。针对系统中存在的不确定性和外部干扰,根据实用稳定理论,分析受控系统的不确定性边界情况,设计自适应律,进而构建自适应鲁棒控制策略。通过开展仿真实验,验证了所设计控制器能克服系统复杂不确定性干扰,促使坦克火炮快速、稳定地调整到期望角度。
Aiming at the problems of the stabilization system of all-electric tank gun,including uncertainty,external disturbance and unsteady tracking moving targets during traveling,an adaptive robust controller was designed to meet performance requiremnets of new generation tank for firing on the move.The nonlinearity,coupling and uncertainty of the artillery stabilization system during traveling was analyzed comprehensively,a dynamic model of the tank bidirectional stabilization system with all-electric actuators was established based on the dynamic characteristics of the servo motor and electric cylinder,and the model was expressed in the form of state space.As for the uncertainty,external disturbance and uncertainty boundary of controlled system was analyzed and an adaptive robust control strategy was constructed based on stability theory,as well as simulation experiments were carried out.The results show that the controller can overcome uncertain disturbance and enable the tank gun to adjust to the desired angle quickly and stably.
