Pressure control of a nonlinear system with a linear-PMSM and a standard inverter
2009 IEEE International Electric Machines and Drives Conference
This paper deals with a high dynamic hydraulic pressure control. The pressure is generated by an inverter driven linear drive which applies a force on a hydraulic cylinder. The linear drive has to generate a pressure profile into the hydraulic system and has to keep it at a constant value after reaching the demanded pressure. The controlled system, containing hydraulic oil, dissolved air and overall three spring packs, is showing a highly non-linear characteristic. The control cascade of thedoi:10.1109/iemdc.2009.5075187 fatcat:gwdgywaa5zcbfl3s3c5z4sn5tu
