On the sixty-four polynomials of Djaferis to stabilize an interval plant
Roberto Hernández, S. Dormido · IEEE Transactions on Automatic Control · 1995
This paper shows that 32 of the 64 polynomials developed by Djaferis to stabilize an interval plant with a controller are superfluous. Thus it is sufficient to stabilize 32 polynomials simultaneously. Moreover the construction developed in this note allows the implementation of these polynomials in a simple way.
