Optimization algorithms for bilinear model-based predictive control problems
DOI:10.1002/aic.10122.png)
摘要
En 中文
Model-based predictive control (MPC) for discrete-time bilinear state-space models is considered. The optimization problem of the bilinear MPC algorithm is nonlinear in general. It is demonstrated that the structural properties of the bilinear state-space model provide a way to formulate the nonlinear optimization problem as a sequence of quadratic programming problems that exactly represent the original objective function. The proposed optimization algorithm is compared to one that is based on a linearization about all input trajectory. To benefit from the advantages of both algorithms, a hybrid algorithm is proposed, which outperforms the other two in most cases. The applicability of the proposed bilinear MPC algorithm is demonstrated on a polymerization process. (C) 2004 American Institute of Chemical Engineers.
