Continuous-time local state local model networks

The continuous-time version of the local model network (LMN) approach of Johansen and Foss is discussed. A distinction is made between local state and global state LMNs; the former turns out to be a form of recurrent net, the latter a form of feedforward net. It is shown how local-state LMN representations of nonlinear systems can be used to design LMN-based controllers via both state observer/feedback. It is suggested that this approach provides an alternative foundation for nonlinear self-tuning control.
