| Abstract: | If the measuring signals were input to the chaotic dynamic system as initial parameters, the system outputs might be in steady
state, periodic state or chaos state. If the chaotic dynamic system outputs controlled in the periodic states, the periodic
numbers would be changed most with the signals. Our novel method is to add chaotic dynamic vibration to the measurement or
sensor system. The sensor sensitivity and precision of a measurement system would be improved with this method. Chaotic dynamics
measurement algorithms are given and their sensitivity to parameters are analyzed in this paper. The effects of noises on
the system are discussed.
