On the stability of quasipolynomials with weighted diamond coefficients
The robust stability of families of time delay systems with multiple interval delays and complex weighted diamond coefficients is considered. Three families of quasipolynomials with weighted diamond coefficients are investigated. Edge-type stability criteria for the quasipolynomials are established. It is shown that regardless of the number of uncertain delays, a testing subfamily of diamond quasipolynomials with interval commensurate delays consists of only eight one-parameter quasipolynomials. If the delays are fixed then the testing subfamily consists of eight quasipolynomials only.
