Application of the Parametric Identification While Modelling the Dynamics of the Electro-Hydraulic Drive
The quality of control systems is one of the most important factors leading to proper operation of electro-hydraulic servo-drives. This paper discusses possibilities to apply the dynamic identification with a discrete linear model while assessing the state of the electro-hydraulic drive dynamics. This evaluation is crucial while designing modern power or positional control systems. Experimental data is applied in order to determine the model dynamics of the real system and estimate unknown parameters of an object model. The dependencies were interpreted. The paper includes the selected results of current identification tests of the electro-hydraulic drive system and based on them the discrete parametric object model was derived.
