✦ Synopsis


Non-linear transient behaviour of #exible structures requires numerical integration of the system's equations of motion. A simpli"ed method for identifying the impulse response function, while avoiding this integration, is presented here. The impulse response function obtained is time dependent and is a characteristic of the global system, remaining valid when reasonable perturbations are applied to external data. Application of this method to the swing of a golfer gives satisfactory results. The implementation of the method as a solution to an inverse dynamics problem, the optimisation process, validation with experimental data, and a potential biomechanical application is discussed.

## Abstract The paper deals with gray box identification of flexible structures and active vibration suppression from a robust control perspective. First, the linearized mathematical model of an __N__‐storey flexible structure is presented. Next, the generalized mathematical model is particularized

This paper presents a method for experimentally identifying the parameters of a lightly damped non-linear system with an odd restoring force, as represented by the Du$ng equation. It requires only a single free vibration test to determine the variation of the natural frequency with the decaying ampl
