Abstract :
The ALSTOM gasifier is a typical multivariable nonlinear system, and is an ideal benchmark for various advanced control strategies. In this paper, relative gain array (RGA) and singular value decomposition (SVD) approaches are applied to analyze the control structure of the ALSTOM gasifier, and parameters are tuned for the resulted decentralized control structures. Simulations show that these structures are not very proper for the decentralized control of the gasifier due to the neglect of system dynamics and the input saturation and rate limit. Further research should be done to obtain a reasonable control structure for the gasifier.
