  3. Abstract:
  4. In this paper, a new fully decentralized control strategy for the ALESTOM gasifier benchmark is presented. The proposed decentralized fault-tolerant control scheme overcomes the conventional drawbacks of the previously developed centralized strategies for the linearized model of gasifier system. To achieve the objective, first, the best pairing has been selected based on integrity screening tools as well as physical considerations. Then, a fully decentralized Proportional Integral (PI) controller has been proposed. Finally simulation results performed in MATLAB show that the designed controller is capable of achieving desired performance for three different scenarios, i.e., full, half and no load system. Moreover the simulation case studies verify integrity of the proposed design against sensor and actuator failures
