Abstract :
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
