摘　　要：针对简易制导弹药制导控制系统中存在的非线性问题,采用描述函数法对含有3种非线性环节的速度矢量驾驶仪进行了设计.同时为了得出较好的设计结果,在描述函数方法的基础上结合非线性方程组的寻优程序,提出了一种非线性制导控制系统的设计新方法,并进行了仿真,验证了该方法的正确性.For the nonlinear problem of simple guided munitions guidance and control system, description function is adopted to design the velocity autopilot including three types of nonlinear sections. At the same time, to obtain a better design result, based on means of description function combining the optimization program of nonlinear equations, a new method for nonlinear guidance and control system design is proposed. With the simulation results it is affirmed that the given method is correct.
