Abstract

For identification of linear continuous system the convolution filter with modulating functions is used. This method transforms differential equation to algebraic one with the same parameters. Two approaches to identification are presented - by the use of equation error method and output error method. The discussion about differences in obtained results of identification is presented especially for different type of parameter constraints.
