Abstract :
In this paper, we study D-stability conditions for sampled control system. There are some interval parameters in the system matrix. In this case, the eigenvalues of system matrix depends on these interval parameters. Firstly, we will show the stability conditions with the monotonicity with respect to interval parameters. Next, we will give an approximated circle for limacon in z-plane. Using simple transformation and above mentioned stability theorem, we can check D-stability in z-plane.
