Strong Kharitonov theorems for low-order polynomials
Y.K. Foo, Yeng Chai Soh · IEEE Transactions on Automatic Control · 1992
The root clustering property of low-order interval polynomials is examined, and it is shown that the number of polynomials required to check root clustering within the left sector may be reduced if the order of the interval polynomial is low. Specifically, the reduction is possible if n phi>
