Abstract :
Identifying the mode of operation of a hybrid system while simultaneously tracking the state is difficult without a direct modal measurement. Even with such a measurement, subtle biases have been observed in applications. It is shown here that for one estimation algorithm, modal identification can be improved with a simple adjustment in the measurement update
