Analysis and Optimization of a Hydraulic-Feedback Proportional Throttlecartridge Valve

Abstract:

In this work, one kind of proportional throttle cartridge valve which is based on hydraulic-feedback principle is studied comprehensively. A detailed precise mathematical model is built. Analysis of the model shows that the model varies greatly depending on the operating point chosen for the linearization. The influences of design parameters are studied through root locus method and several parameters are picked out which have great impact on the dynamic performance. Then an optimization based on iterative eigenvalue configuration is implemented. After the optimization, the performance of the valve is improved effectively.
