【Abstract】 The chaotic system will bifurcate when the system parameters change a little.If the measured signal was put to the chaotic system,it would be get the stable state,period states and chaotic states.In the article,controlling the system work at the period states makes the states changes with the signal,A chaotic circuit has been added to the measurement system to improve the delicacy.The measurement delicacy was analyzed.The results of chaotic system immuned with the noises were given.更多还原
