Problems solved by technology

The temperature control system contains a pure hysteresis link, the heating / cooling actuator has a certain inertia, the inhomogeneity and thermal inertia of the controlled object, as well as the load change and external disturbance, which are easy to cause the system overshoot and oscillation and the change of the system parameters. This random and unpredictable change will undoubtedly increase the difficulty of realizing high-precision temperature control

Abstract

The invention provides a passive variable-thermal-resistance temperature control two-position regulating method. A semiconductor temperature difference module realizing passive variable thermal resistance is arranged among a temperature control object, and a heating executer and a refrigerating executer of a temperature control device. According to collected temperature signals, the thermal resistance is controlled to be minimum and maximum through two-position regulation, so that the heat flow is changed, and the temperature control is realized. The two-position control cost is low; the realization is easy; high cost performance is realized; the two-position control of the semiconductor temperature difference module is combined, no motion component is used, and no deviation middle regionexists, so that the control precision is higher; and if the two-way active temperature control of the semiconductor refrigeration is matched, the temperature control precision can be further improvedthrough the variable thermal resistance. The temperature control precision is effectively improved; and the method can be widely applied to the high-precision temperature control of different temperature regions.

Description

technical field [0001] The invention relates to a two-position adjustment method for passive variable thermal resistance temperature control, in particular to a two-position adjustment method for the passive variable thermal resistance temperature control method based on a semiconductor temperature difference module. Background technique [0002] Temperature is the most important controlled parameter, and high-precision temperature control has extremely wide application requirements and prospects. The temperature control system contains a pure hysteresis link, the heating / cooling actuator has a certain inertia, the inhomogeneity and thermal inertia of the controlled object, as well as the load change and external disturbance, which are easy to cause the system overshoot and oscillation and the change of the system parameters. This random and unpredictable change will undoubtedly increase the difficulty of realizing high-precision temperature control. [0003] The two-positi...
