摘要 在实时子结构试验中,如果加载作动器不能及时、准确、稳定地实现在算法步长内的动作指令或者在加载过程中受到扰动,那么将造成试验结果的极大失真。为了避免这种情况的出现,创新的将Popov超稳定理论引入到试验的加载控制中来,设计出了一种MRAC(模型参考自适应控制)系统并通过MATLAB/Simulink进行了建模仿真。仿真结果证明了基于超稳定理论设计的MRAC系统具有良好的跟踪精度、响应速度和在线纠偏功能,满足了实时子结构试验要求。 In real-time substructure testing,if the loading actuator cannot achieve action commands in time and correctly in an algorithm step or is disturbed in a loading process,it may cause a great distortion of test results.In order to avoid the occurrence of such a situation,Popov super stability theory was introduced into the loading control of tests.A model reference adaptive control(MRAC)system was designed and with MATLAB /Simulink,its modeling and simulation were conducted.The simulation results showed that the MRAC system designed using the super stabilitr theory has better tracking accuracy,response speed and online error-correcting function to meet the requirements of real-time substructure testing.
