Abstract:

To solve the electrohydraulic servo-loading extra force problem, in this paper, a new control method is presented through feedback internal different force signals in loading system to suppress the extra force. To overcome the effects of the nonlinearity, parameter’s time variation and uncertainties, the neuralnetwork adaption based on internal reference model control scheme is further proposed in servo loading.
