摘　　要：A new method of applying linear matrix inequalities (LMIs) to multi-objective eigenstructure assignment is put forward. Since there is always a degree of freedom in eigenstructure assignment using state or output feedback, it is available to use this kind of freedom in designing a system to satisfy some additional specializations. With the help of LMI technology, a controller insensitive to pertubation and good in robust stability is realized. And the result of a practical example shows that the method is very useful in flight controller design.A new method of applying linear matrix inequalities (LMIs) to multi-objective eigenstructure assignment is put forward.
