Abstract :
In this paper, the method of approach as used in Qiu and Davison (1992) and Hu and Davison (2000) is extended to the case of delay and neutral type quasi-polynomials. We develop a unified approach to compute the stability robustness measure of quasi-polynomials in a convex set using the framework of convex analysis. The procedure to compute the stability robustness measure which results from this approach is easy to implement. Finally, an example is given to demonstrate the effectiveness of this approach
