Application of Robust Multivariable Control to a Fluidized Bed Combustor for Sewage Sludge

摘要

Based on the experimental data, a fluidized bed combustor is modelled as an interval system. Severe model uncertainties and large time delays lead to the main difficulties in solving the control problem. The design uses the robust stability testof the closed-loop system as the main guideline to develop a robust controller. Both the theoretical and the experimental results show that the designed controller meets the performance requirements.
