| Abstract: | By studying the properties or the phase angle and the phase angle velicity of polynomials in the frequency domain, a simple algorithm is given for dertermining the D-stability of a polytopc of potynomials, and some sufficient conditions and a necessary and sufficient condition are then obtained for the D-stability or convex combinations of sta- ble polynomials. These conditions are quite useful for seeking the vertex results in checking the robust stability of the systems. |
