Abstract: Systems and methods for dynamic force measurement are disclosed. A method in accordance with one embodiment includes applying forces to a model in at least one direction at at least one location, receiving information from at least one sensor, and identifying a math model of a model support structure. In particular embodiments, the method can further include generating a force estimator. In further particular embodiments, the method the force estimator can be an optimal unbiased minimum-variance input and state estimator based on a linear time invariant math model taking the form of a digital filter.
