We developed an on-line experimental system for conducting hybrid experiments in real time. This. system combines a computer for simulating vibration and generating a control signal with an actuator for vibrating a structure according to the control signal. And the system compensates for actuator delay, so that experiments can be carried out in real time. In this report, we discuss the stability ciriterion with respect to the mass of the structure under excitation in conducting real-time hybrid experiments, and propose a new method for compensating actuator delay so the experiments are more stable. This method increases the stability criterion (the allowable ratio of the mass of the structure under excitation to that of the mumerical model) by about three times compared with that of the conventional method.
