Abstract :
The paper state that the original authors´ results for systems without uncertainties or without uncertainties in the measurement are necessary and sufficient and the proofs are correct. However, when in addition the uncertainties appear in the output, the results are only sufficient. The necessity in the latter case still an open problem even in the quadratic stability.
