Generalized Bilinear System Identification
- 63 Downloads
A novel method is presented for identification of a bilinear system generalized to include higher-order input coupling terms. It derives from an existing method for identification of a continuous-time bilinear system. The method first generates a set of pulse responses from a constant input over a sample period for identification of the state matrix, the output matrix, and the direct transmission matrix. The method then produces another set of pulse responses with the same constant input over varying sample periods for identification of the input matrix and the coefficient matrices associated with the coupling terms between the state and the inputs. A simple example is given to illustrate the concept of the identification method.
