A new algorithm for criticizing robust D stability of uncertain control systems

This paper presents a new algorithm of robust D stability analysis based on engineering application. The algorithm has apparent superiority in the field of computation comparing with other methods as far as the perturbed parameters increase. It is not only suitable for the robust D stability analysis of interval polynomial family but also for the polytopic polynomials, and it has also been extended into the robust D stability analysis of the polytopic polynomials with time delays. It is suitable for both continuous-time and discrete-time systems and makes the robust theory take a step towards the engineering application.<>
