摘　　要：混合试验通过模拟与试验的结合,大大降低了对设备的要求及试验成本,得到了较快发展.为了提高试验的可靠性并降低试验难度,试验的加载控制误差需要得到有效控制,并把相关方法集成到试验软件平台.本文以混合试验软件HyTest的控制方法为中心,综述了外环控制、外环位移-内环力控制、三自由度控制方法及相关试验.试验数据检验了方法的有效性,并表明不同方法的特点.多种控制策略可供选择是HyTest突出特点之一。Hybrid testing has been developed rapidly since it combines numerical simulation and physical experiment, which can greatly reduce the cost of tests and demands for equipment. In order to improve the reliability of hybrid tests, loading errors should be effectively controlled. Meanwhile,the corresponding schemes should be incorporated into testing software to reduce complexity of conducting hybrid testing. This paper reviews several outer loop control methods implemented on a platform for hybrid tests called HyTest and test results with these methods. These control strategies include the outer loop control method,the outer displacement - inner force control method and the three-DOF control method. Test results validated the effectiveness of different methods and showed different features. Several control strategies are available for users of HyTest ,which is concluded as one of the outstanding features of HyTest.
