基于输入输出线性化方法的制导弹药姿态控制系统设计

The Design of Attitude Control System of Guidance Ammunition based on Input and Output Linearization Method

根据姿态运动学模型,分析了现代制导的弹药,飞行速度远远高于传统导弹,因此一般都要求具有快速的动态响应特性,来实现系统输出快速跟踪预测制导指令期望值。用输入输出线性化可以有效地代数补偿非线性系统模型具有线性的传递关系。进行了仿真验证,验证了方法的可行性。

This paper analyzes the modern guidance ammunition according to the attitude kinematics model. The flight speed of modern guidance ammunition is much higher than that of conventional missile. So it is generally required to have fast dynamic response characteristics which can achieve fast tracking of predictive guidance expectations of system output. With the input and output linearization, it is can effectively compensate the nonlinear system model with linear transfer relationship in an algebraic way. This paper carries on a simulated verification to verify the feasibility of the method.
