Abstract:
This paper presents a model-based control strategy for usage in multilevel pressure boosting systems with centrifugal pumps operating in parallel. The control is based on a nonlinear system model using exact input-output linearization. With the help of an optimization algorithm, the total consumption flow rate is distributed optimally in such a way that the total hydraulic efficiency of all running pumps is maximized in steady state while complying with all constraints. Trajectories for every single pump are planned on model-based relations in order to reduce overshoots in the pipeline pressure, in particular during start-up processes. The whole control strategy is validated on a test bench.
