摘要：AbstractThis paper proposes a model-based robust adaptive control (MB-RAC) which is derived from the L1robust adaptive control (L1-RAC). By inheriting excellent control performance from the L1-RAC for systems with nonlinearity and uncertain conditions, the MB-RAC offers its own feature for dealing with a long time delay by using dual-feedback adaptive law from the built-in model and the plant. A nonlinear boiler-turbine-generator unit augmented with time delays is adopted as the plant for verifying the MB-RAC. Simulation results present good control performances of the MB-RAC in a wide-range load-following process with long time delays and show its strong robustness to inner model mismatches from the plant on both dynamics and time delays. The MB-RAC is shown to be reliable and easy to implement for industrial processes.
