An optimal method is developed to estimate the dynamic loads for systems subjected to multiple inputs. The method focuses on minimizing the ensemble mean square error of the estimation. First, the inverse system analysis technique is employed to establish the error estimation equation. Then, by applying the noncausal Wiener filtering theory, the optimal estimator of dynamic loads is derived out. Both numerical simulation and experimental results demonstrate that the method is of a good ability in suppressing the influence of measurement noises than conventional methods, which based on solving inverse matrix of transfer function, and is rather effective and practicable for dynamic load estimation.
