Development of Simulation Program “BDSP” for Hydraulic Control Systems (Evaluation of the Functions for Identifications of System Parameters and Models)

This study deals with a software package named “Block Diagram Simulation Program (BDSP)” which is being developed in Gifu University, Japan. In the last study, we added the identification function that identifies the system parameters in the some hydraulic systems. However, it is difficult to get the appropriate simulation results by using the identified parameters. Therefore we add the new function of the system identification, that is to identify the dynamics responses of the system from the relationships between the input to system and output from system. In this paper, the functions for identification of system parameters and models are evaluated.
