Gain scheduled velocity and force controllers for the electro-hydraulic servosystem
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002 The load variation of the electro-hydraulic servosystem causes degradation of the control characteristic. This is because the flow characteristic of the flow control valve depends on the load condition. Here, we propose the flow calculation formula to have continues flow between turbulent and laminar flow so that compose the linear plant model with a ...
