Abstract: The possibility to use robust PI controllers for stabilization of continuous stirred tank reactors is discussed in this paper. Considered reactors are exothermic ones with multiple steady states and uncertain parameters. A computationally simple non-iterative algorithm is used for the robust static output feedback PI controller design. The design procedure guarantees with sufficient conditions the robust quadratic stability and the guaranteed cost. Designed robust PI controllers are able to stabilize the reactors with uncertainty in their unstable steady states.

Keywords: chemical reactor, PI controller, robust control, static output feedback
