摘　　要：高速机动的火箭武器具有很强的非线性,传统的小扰动线性化方法不再适用,为了解决这一类问题,文中引入微分几何方法。微分几何方法能实现对火箭飞行时,三通道间强烈耦合的非线性系统的解耦和精确线性化,采用这一方法解决非线性系统的耦合问题,并给出了仿真实例,仿真结果表明了该方法的可行性。The rocket weapon with high-speed maneuverability is strong nonlinear, and the traditional linear method with little disturb does not fit anymore. So the geometry method was introduced. The differential geometry method can realize decoupling and precisely linear for strong coupling nonlinear system. The method was adopted to solve the nonlinear system＇s coupling problem and simulation results indicate that the method is feasible.
