Abstract

The paper aims at piloted electro-hydraulic proportional pressure-reducing valve characteristics of uncertain parameters, immeasurable states and effect of load flow, designed an observer including load flow and it’s feedback controller ,achieve robust output-feedback control to the output pressure .Based on linear matrix inequalities, theoretical analysis showed that the system was stable and had robust H-infinity performance , given the method to obtain the observer gain L and controller gain K. By simulating a certain proportional pressure reducing valve, verified the validity of the algorithm, eliminated the influence of load flow to output pressure and ensured it following the set pressure quickly.
