中文摘要:
针对固定翼双旋弹修正组件滚转通道存在的输入扰动和模型不确定性问题，设计一种基于H∞回路整形的两自由度滚转通道控制方法. 通过对修正组件电气系统和机械系统的建模，得到执行机构电磁控制力矩的计算方法，利用理论分析及实验测试，研究了修正组件气动力矩和滚转阻尼力矩的建模方法，从而得到滚转通道控制模型，并设计基于H∞回路整形的两自由度滚转通道控制器实现滚转角度控制. 半实物仿真实验结果表明，通过对修正组件电气系统和机械系统分析建立滚转通道控制模型的方法可行，设计的滚转通道控制器能够实现精确的滚转角控制.
English Summary:
In order to solve the input disturbance and model uncertainty problems of the roll channel of the course correction fuze (CCF) for dual-spin projectile with fixed-canards, a two-degree-of-freedom roll channel control method based on H∞ loop shaping was proposed. Through the modeling of electrical and mechanical systems of the CCF, the calculation method of the electromagnetic control torque of the actuator was researched. Based on theoretical analysis and experimental test, the modeling method of the aerodynamic torque and the rolling damping torque of the CCF were studied, and then the roll channel control model was obtained. A two-degree-of-freedom roll channel controller based on H∞ loop shaping was designed to control the roll angle of the CCF. Hardware-in-the-loop simulation experiments show that it is feasible to establish the roll channel control model by analyzing the electrical and mechanical systems of the CCF, and the designed roll channel controller can achieve accurate roll angle control.
