Identification of a micro-thrust array test stand and its dynamic error compensation

A dynamic force test method was modified for application in the new micro-thrust array test stand so as to solve an irrational problem. The simplified test stand is used for modal mode by using ANSYS. The results verify that mode analysis is correct. The method applying step force on the test stand was improved, i.e. the quasi-step force can be applied by burning strings. The system model was obtained. According to the theoretical model, inverse transfer function compensation method was used for dynamic compensation of signal so as to improve dynamic performance of test system greatly.
