An approach to robust multivariable combustion control design

Two robust controller structures are presented. These two structures affect the process in different ways, and so both could be joined together to give more robust control than each controller separately. The structure was used for combustion control which represents multivariable and nonlinear problems with time delay. Simulation results for a closed-loop control system are presented and discussed. The procedure for designing robust multivariable control was supported with computer-aided control system design tools
