Abstract :
The paper describes a software package AISTK (Analysis of Interval Systems Toolkit) developed for the analysis of interval systems. The package has been developed in the MATLAB environment with a powerful graphical user interface. The procedures for constructing various envelopes that contain the entire frequency responses of the interval systems are given. The outer boundary of the Nyquist envelope which is generated by a stable interval plant is also discussed by using generalized Hermite-Biehler-Mikhailov stability criterion or interlacing frequency band criterion
