Modeling, Simulation, and Control Concepts for a Hydraulic Supply Unit to Control Pressure or Flow Rates
Englische Kurzfassung:
This summary discusses the development, implementation and investigation
of a signal-processor based digital controller which interfaces with an existing
hydraulic supply unit thus increasing its overall system performance. The major
objective is to control pressure-level or flow-rate at a point of interest
within a hydraulic system (normally outside of the supply unit). Conventional
hydro-mechanical components, such as pressure limiting valves or proportional
valves, do not achieve satisfactory results. Consequently, a mechatronic approach
suggests the use of a digital controller to adjust the supply unit's state so that
the desired pressure or flow-rate at this point of interest can be kept within
reasonable limits. Investigations based onto the laboratory system have shown
that pressure deviations were well within
+/- 0.45 bar and flow-rate errors within
+/- 0.45 l/min for given disturbances resulting in an significant increase of the
overall system performance up to a factor of ten.
