Optimal control of transient thermoelectric cooling process in the mode of minimum power consumption
Keywords:
transient thermoelectric cooling, optimal control, optimal time dependences of thermoelement supply currentAbstract
The problem of optimal control of transient thermoelectric cooling process in the mode of minimum power consumption is formulated and a method for its solution is proposed. An algorithm and a computer tool have been developed, which are used to calculate the optimal time dependences of the thermoelement supply current, whereby a given cooling temperature is reached within a given time with minimum power consumption. Examples of computer simulation of such optimal control functions for transient cooling process are given. It has been established that energy saving when supplying thermoelements with an optimally time-dependent current reaches 25 – 50 % in comparison with the option of direct current power supply.
