Abstract

This paper presents a proportional-integral (PI) controller design approach using multi-objective optimization which addresses the ALSTOM benchmark challenge on gasifier control. The non-linear gasifier has been linearized about three operating points. The design aim is to satisfy a set of specifications on the system outputs, inputs and input rates when a step disturbance is applied to the system. The parameters of the multiple-input multiple-output (MIMO) PI controller are selected to satisfy a set of multi-objective performance criteria, which are formulated from the system specifications. Simulation results are presented which demonstrate the performance of the controller at the three operating points.
