Abstract
A nonparametric time-varying system identification technique has been developed to identify instantaneous impulse response functions of a system undergoing abrupt changes of state using ensemble input and output records. No a priori assumptions are required regarding system structure, form of nonstationarity, or input characteristics. Experimental studies have shown the method to be capable of tracking the time course of changes in human ankle joint dynamics associated with an abrupt change in the level of voluntary activation
