%X Absorption heat devices are affected by varied operating conditions. An adaptive control system was developed, which adapts itself to the circumstances in the process, and implemented on the one-stage laboratory heat pump with a H2O-LiBr working pair. The control system was adapted on the basis of the information on the process from the dynamic model of the process. This was estimated in real time by recursive parametric identification using the least-squares method with a variable forgetting factor. The controller parameters were adjusted according to the appropriate closed loop control law, in which a cancellation controller with pole-zero placement was used. An adaptively controlled absorption heat pump is capable of operating within a wide range of working conditions without considerable oscillations of its properties. The control system was distinguished by good compensation of both external and internal disturbances of different amplitudes and frequencies. It is suitable for the control of similar processes, since it contains mechanisms for the identification of model structure, and does not demand a priori knowledge o f the physical properties o f the process.

Absorption heat devices are affected by varied operating conditions. An adaptive control system was developed, which adapts itself to the circumstances in the process, and implemented on the one-stage laboratory heat pump with a H2O-LiBr working pair. The control system was adapted on the basis of the information on the process from the dynamic model of the process. This was estimated in real time by recursive parametric identification using the least-squares method with a variable forgetting factor. The controller parameters were adjusted according to the appropriate closed loop control law, in which a cancellation controller with pole-zero placement was used. An adaptively controlled absorption heat pump is capable of operating within a wide range of working conditions without considerable oscillations of its properties. The control system was distinguished by good compensation of both external and internal disturbances of different amplitudes and frequencies. It is suitable for the control of similar processes, since it contains mechanisms for the identification of model structure, and does not demand a priori knowledge o f the physical properties o f the process.
