GRANADO, ERNESTO; COLMENARES, WILLIAM  e  PEREZ, OMAR. Robust multivariable pid design via iterative lmi. Rev. Fac. Ing. UCV [online]. 2007, vol.22, n.3, pp.5-12. ISSN 0798-4065.

This paper presents the design of a robust multivariable PID controller, which guarantees the stability of the closed loop linear systems subjected to polytopic uncertainty. The algorithm is based on an Iterative Linear Matrix Inequality (ILMI) approach. The obtained results may also be used to compute a static output feedback stabilizing controller. The design technique is illustrated with numerical examples.
