Abstract
Taylor, C.J., McCabe, A.P., Young P.C. and Chotai, A., (2000), Proportional-Integral-Plus (PIP) control of the ALSTOM gasifier problem, Proceedings of the Institution of Mechanical Engineers, Journal of Systems and Control Engineering, 214, Part I, 469-480. (ISSN: 0959-6518).
| Although it is able to exploit the full power of optimal state variable feedback within a Non-Minimum State Space (NMSS) setting, the Proportional-Integral-Plus (PIP) controller is simple to implement and provides a logical extension of conventional PI/PID controllers, with additional dynamic feedback and input compensators introduced automatically by the NMSS formulation of the problem when the process is of greater than first order or has appreciable pure time delays. The present paper applies the PIP methodology to the Alstom benchmark challenge, which takes the form of a highly coupled, multivariable linear model, representing the gasifier system of an Integrated Gasification Combined Cycle (IGCC) power plant. In particular, a straightforwardly tuned, discrete-time PIP control system based on a reduced order, backward shift model of the gasifier, is found to yield good control of the benchmark, meeting most of the specified performance requirements at three different operating points. |
