RESUMO

This Dissertation is focused on control system design and stability analysis of linear timeinvariant uncertain plants, with uncertainties of interval nature. The control system design problem is treated in the context of the pole placement technique. An extension of the classical technique to robust pole placement based on Interval Analysis is proposed. The main objective of the work is to handle multiple incidences of plant parameters in order to reduce the radii of the solutions of the resulting interval Diophantine equations. Another subject treated is the design of robust controllers for interval plants which guarantee reference tracking and disturbance rejection asymptotically. The stability of linear interval systems as the problem of finding a symmetric positive definite interval solution of an interval Lyapunov equation is also considered
