Frequency domain criteria for strict aperiodicity of linear interval systems
CHEONG BOON SOH · International Journal of Systems Science · 1993
Interval systems arise when systems experience parameter variations. This paper derives frequency domain criteria for interval systems to be strictly aperiodic. The frequency domain criteria only requires one frequency domain plot to check for strict aperiodicity of linear interval systems. Furthermore, the largest allowable perturbation bounds can be graphically estimated from the same frequency domain plot.
