为了设计某型制导火箭弹的控制系统,并仿真验证其动态性能,文中首先由火箭弹运动方程建立其运动数学模型,在小扰动前提下,采用系数冻结法对运动方程进行线性化,求解出弹体传递函数。利用Simulink控制系统工具箱,建立控制系统仿真模型,由SignalConstraint模块优化出控制系统的参数。仿真结果表明,该控制系统结构及参数设计合理,动态性能良好,为下一步研究奠定了良好的基础。

In order to design the control system for a guided rocket and ensure that it takes on favorable dynamic performance, the design and simulation of the control system was described. The mathematical model of the rocket was established on the basis of its motion equations, from which the transfer function of the body was deduced. Small disturbance precondition and frozen coefficient method were used in the process of derivation. Then the simulation model was built under Simulink environment, and the parameters of the control system were optimized by using Signal Constraint Module. The simulation results indicate that the control system works well and lays a foundation for further research.
