摘要：Instead of establishing mathematical hydraulic system models from physical laws usually done with the problems of complex modelling processes,low reliability and practicality caused by large uncertainties,a novel modelling method for a highly nonlinear system of a hydraulic excavator is presented.Based on the data collected in the excavator's arms driving experiments,a data-based excavator dynamic model using Simplified Refined Instrumental Variable(SRIV)identification and estimation algorithms is established.The validity of the proposed data-based model is indirectly demonstrated by the performance of computer simulation and the real machine motion control experiments.
