Multiobjective optimisation approach to robust controller design
Multiobjective optimisation approach to robust controller design
A control system design procedure based on the optimisation of multiple objectives is used to address the control design requirements of a simulated gasification plant. The non-linear gasifier is represented by three linear models relating to three separatge operating points. The H_LSDP is used to guarantee the stability of the linear controller at its design point while the multiobjective (MO) search method is used in order to optimise the robustness of the controller in terms of both stability and performance. A linear controller emerges that provices closed loop stability at all three operating points and is capable of meeting all the performance requirements except for those of the gas pressure at the 0% load operating point.

Abstract
A control system design procedure based on the optimisation of multiple objectives is used to address the control design requirements of a simulated gasification plant. The non-linear gasifier is represented by three linear models relating to three separatge operating points. The H_LSDP is used to guarantee the stability of the linear controller at its design point while the multiobjective (MO) search method is used in order to optimise the robustness of the controller in terms of both stability and performance. A linear controller emerges that provices closed loop stability at all three operating points and is capable of meeting all the performance requirements except for those of the gas pressure at the 0% load operating point.
