Abstract
This paper uses convex analysis for the pole assignment design of disc rete-time SISO systems incorporating robust stability against norm bou nded parametric perturbations in the plant transfer function. The meth od involves designing an overparameterized pole assignment controller for the nominal plant with the overparameterization chosen to reduce t he size of changes in the closed-loop characteristic equation which re sult from plant perturbations. Sufficiency bounds on the l(p) norm of the perturbation guaranteeing stability are obtained.
