The control actions are usually computed by regularly solving an on-line optimisation problem in the discrete-time space based on a set of measurements that specify the current process state. A way to derive the explicit optimal control law, thereby, eliminating the need for rigorous on-line computations has already been reported in the literature, but it is limited to discrete-time linear dynamic systems. The currently presented approach derives the optimal state-feedback control law off-line for a continuous-time dynamic plant representation. The control law is proved to be nonlinear piecewise differentiable with respect to the system state and does not require the repetitive solution of on-line optimisation problems. Hence, the on-line implementation is reduced to a sequence of function evaluations. The key advantages of the proposed algorithm are demonstrated via two illustrative examples.}, year = {2005}, pages = {443-452} } @article{MTMT:20823792, title = {On the interpretation and practice of dynamical differences between Hammerstein and Wiener models}, url = {https://m2.mtmt.hu/api/publication/20823792}, author = {Aguirre, L A and Coelho, M C S and CorrĂȘa, M V}, doi = {10.1049/ip-cta:20045152}, journal-iso = {IEE P-CONTR THEOR AP}, journal = {IEE PROCEEDINGS-CONTROL THEORY AND APPLICATIONS}, volume = {152}, unique-id = {20823792}, issn = {1350-2379}, year = {2005}, pages = {349-356} } @article{MTMT:10279560, title = {Fault detection for Markovian jump systems.}, url = {https://m2.mtmt.hu/api/publication/10279560}, author = {Zhong, M and Ye, H and Shi, P and Wang, G}, journal-iso = {IEE P-CONTR THEOR AP}, journal = {IEE PROCEEDINGS-CONTROL THEORY AND APPLICATIONS}, volume = {152}, unique-id = {10279560}, issn = {1350-2379}, year = {2005}, pages = {397-402} } @article{MTMT:32207485, title = {Nominal stability of real-time iteration scheme for nonlinear model predictive control}, url = {https://m2.mtmt.hu/api/publication/32207485}, author = {Diehl, M and Findeisen, R and Allgower, F and Bock, HG and Schloder, JP}, doi = {10.1049/ip-cta:20040008}, journal-iso = {IEE P-CONTR THEOR AP}, journal = {IEE PROCEEDINGS-CONTROL THEORY AND APPLICATIONS}, volume = {152}, unique-id = {32207485}, issn = {1350-2379}, abstract = {A Newton-type method is investigated for online optimisation in nonlinear model predictive control, the so-called real-time iteration scheme. Only one Newton-type iteration is performed per sampling instant in this scheme, and control of the system and the solution of the optimal control problem are performed in parallel. In the resulting combined dynamics of system and optimiser, the actual feedback control in each step is based on the current solution estimate, and the solution estimates are at each sampling instant refined and transferred to the next optimisation problem by a specially designed transition. This approach yields an efficient online optimisation algorithm that has already been successfully tested in several applications. Due to the close dovetailing of system and optimiser dynamics, however, stability of the closed-loop system is not implied by standard nonlinear model predictive control results. A proof of nominal stability of the scheme is given which builds on concepts from both NMPC stability theory and convergence analysis of Newton-type methods. The principal result is that, under some reasonable assumptions, the combined system-optimiser dynamics can be guaranteed to converge towards the origin from significantly disturbed system-optimiser states.}, year = {2005}, pages = {296-308}, orcid-numbers = {Findeisen, R/0000-0002-9112-5946; Allgower, F/0000-0002-3702-3658} } @article{MTMT:34467161, title = {Process fault isolation for linear systems with unknown inputs}, url = {https://m2.mtmt.hu/api/publication/34467161}, author = {Park, TG and Lee, KS}, doi = {10.1049/ip-cta:20040796}, journal-iso = {IEE P-CONTR THEOR AP}, journal = {IEE PROCEEDINGS-CONTROL THEORY AND APPLICATIONS}, volume = {151}, unique-id = {34467161}, issn = {1350-2379}, abstract = {A systematic and straightforward fault estimation approach for process fault detection, isolation and accommodation is presented.
