Identification of continuous-time systems with multiple unknown time delays

Abstract

Purpose

The purpose of this paper is to present a separable identification algorithm for a multiple-input single-output (MISO) continuous-time (CT) system.

Design/methodology/approach

This paper proposes an optimal method for the identification of MISO CT systems with unknown time delays by using the Simplified Refined Instrumental Variable method.

Findings

Simulations results are presented to show the performance of the proposed approach in the presence of additive output measurement noise.

Originality/value

This paper presents an optimal and robust method to separable delays and parameter identification of a MISO CT system with unknown time delays from sampled input/output data.
