基于滑模变结构的一类非最小相位系统控制

首先,对一类非最小相位的非线性系统模型进行了描述;然后,基于反馈线性化的思想将其转换为规范型,提出了采用滑模面对其输出进行了重定义设计的一种复合控制方案;最后,为了验证该复合控制的有效性和正确性,基于某型导弹的非最小相位系统进行了仿真计算.仿真结果表明,该复合控制算法具有较高的控制精度.

Composite Control to Certain Non-Minimum Phase System

First,the model of certain non-minimum phase system was described.Then based on feedback linearization theory,it was transferred to criterion model,and a new integrated control scheme of the terminal sliding mode output redefinition was presented.Finally,to verify the effectiveness and rightness of the integrated control design scheme,the simulation of some missile non-minimum phase system was made and the simulation results showed that the integrated control approach was of high accuracy.
