ABSTRACT:
A stability control system for a vibration test device having an acceleration control system and using an electro-hydraulic servo-system is disclosed. The stability control system comprises a model operation circuit which simulates a model response corresponding to value representing the states of a vibration table in response to command signals produced from a signal generator and associated with the displacement, velocity and acceleration of the table, and a gain-adjusting circuit which produces gain-adjusting signals to gain-adjusting sections in response to model response signals produced from the model operation circuit, state-representing signals produced from a feedback circuit and the command signals produced from the signal generator. The gain of each gain-adjusting section is automatically controlled in such a manner that the state-representing values of the parts of the control system coincide with the corresponding state-representing values in the model operation circuit.
