Several algorithms are presented for identifying linear continuous MIMO systems and systems with time delay from samples of input-output data. The basis of these algorithms is the corresponding difference equation of the continuous systems using block-pulse functions. The recursive algorithms for determining the transfer function matrix in MIMO systems and in systems with known time delay are simpler than other algorithms based on the operational properties of orthogonal functions, and are easy to implement on-line. The algorithms for identifying systems with unknown time delay are also easy to implement owing to the simple and straightforward treatment of input-output data. Illustrative examples show that these algorithms give satisfactory results for certain identification problems.
