摘　　要：为了抑制火箭炮位置跟踪控制中安装平台耦合动力学和运动学因素对控制精度的影响,建立了基于永磁同步电机(PMSM)的一体化系统数学模型,并将输出调节方法应用到该问题的研究中,针对输出调节方法需要已知外部干扰信号的频率信息和自适应内模收敛速度慢的局限,设计了综合频谱分析、状态观测器和不变流形的反馈控制策略,解决了实时估计外部信号频率问题。仿真分析和试验结果表明,该控制策略抑制外部扰动影响效果明显,提高了火箭炮跟踪精度和稳定性。To restrain the influences of both dynamics and kinematics disturbances from platform on the control precise of a muhitube rocket launcher, a mathematical model of integrated system was established on the basis of permanent magnet synchronous motor （PMSM） , and an output regulation method was ap- plied. Because of requirements of exactly known the frequency information of external disturbance and slower convergence of adaptive internal model in normal output regulation problem （ORP） , a novel out- put feedback regulation strategy was designed, including spectrum analysis to estimate the frequency of external disturbance signal, state observation and invariant manifold. Simulation and experiment results demonstrate that the proposed control strategy performs well in depressing the coupling disturbance of rocket platform, and improves the tracking precise and stability of rocket launcher.
