This paper addresses the problem of time-delay estimation in the specific case of structures with combined feedback/feedforward control. In the case of closed loop single-input/single-output systems, several methods have been developed in order to estimate the time-delay. In particular, this parameter may be determined by using a correlation analysis proposed by Zheng and Feng (1990). The purpose of this work is to generalize the latter approach to the case of feedback/feedforward systems (with two inputs: the control input and the measured disturbance). This is motivated by an application to a managed river reach in passive experimental conditions.
