基于混合灵敏度下H_∞控制在三滑块质量矩导弹上的应用

The Use of H_∞ Control Theory Based on the Mixed-Sensitivity Control for the Mass Moment Missile with Three Masses

由于质量矩导弹是一个具有非线性和模型不确定性的多变量系统,为了进一步提高控制系统的鲁棒性,对三滑块质量矩导弹进行了鲁棒控制系统的研究。以所建立的质量矩导弹数学模型为基础,通过对模型合理的简化,得到一个耦合的非线性动力学系统,考虑到质量矩导弹的鲁棒性要求和三个滑块的协调控制问题,在混合灵敏度控制的基础上,采用H∞控制理论对导弹进行姿态控制系统的研究,仿真结果验证了这种方法的有效性。

For the mass moment missile is a system with nonlinear and model uncertainty, to improve the robustness of the control system further, the robust control system is studied for the mass moment missile with three masses. Based on the constructed model of mass moment control for missile, presents a coupled nonlinear dynamic system by rational simplifying. With the request of robustness of the system and the co-ordination of the control of the three masses, uses H∞ control theory based on the mixed-sensitivity control to study the mass moment attitude control. The simulation results illustrate the efficiency of this method.
