摘要
以所建立的质量矩导弹数学模型为基础,通过对模型合理地简化,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两个滑块伺服机构的协调控制问题,用基于反馈线性化的非线性控制理论,采用非线性预测控制,解决了质量矩导弹姿态控制系统设计问题,并且系统对于参数的不确定性具有很强的鲁棒性.仿真结果检验了这种方法的有效性.
Based on the constructed model of mass moment control for missile, a coupled nonlinear dynamic system is presented by rational simplifying. With the request of robustness of the system and the coordination of the control of the two masses, nonlinear control theory of feedback linearization and nonlinear predictive control are used to solve the problem of the design of the mass moment attitude control, and the system has good robustness in the presence of uncertainty of parameters. The simulation results prove the efficiency of the method.
