Abstract

In this work, a System Dynamics viewpoint is used to examine the stability and performance of a class of hydraulic devices. These devices use hydraulic amplification to command motion of large objects using relatively low level signals. A model is constructed and used for both analysis and simulation of system performance. The analysis is from a linear Classical Controls perspective and is found to be sufficient despite the nonlinear nature of the systems. The analysis is used to consider design changes to the valve components and their resulting effects. Even though the subsystems consist of stable individual components, their interconnection can lead to undesirable performance, or even instability, if the individual dynamics are improperly matched.
