Abstract

This paper investigates decentralized control
structures for absorption cycle heat pumps and a dynamic
nonlinear model of a single-effect LiBr-water absorption system
is used as case study. The model has four controllable inputs,
which can be used to stabilize the operation of the heat pump
under different load conditions. Different feasible input-output
pairings are analyzed by computation of relative gain array
matrices and scaled condition numbers, which indicate the
best pairing choice and the potential of each input-output
set. Further, it is possible to minimize the effect of cross
couplings and improve stability with the right pairing of
input and output. Simulation of selected candidate input-output
pairings demonstrate that decentralized control can provide
stable operation of the heat pump.
