Abstract

The invention belongs to the field of automatic control, and specifically discloses a small-amplitude rapid temperature control device and method. The method includes: obtaining the real-time temperature of the controlled object, and recording the initial temperature of the controlled object; responding to the fact that the initial temperature is lower than the set temperature relative to the target temperature, heating the controlled object; recording the minimum temperature during the heating process; and responding When the real-time temperature is greater than the sum of the minimum temperature and the floating value, stop heating the controlled object. The invention can make the temperature of the controlled object approach the target temperature quickly, and effectively reduce the temperature overshoot in the control process.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to a small-amplitude fast temperature control device and a small-amplitude fast temperature control method. Background technique [0002] In the field of automatic control, PID closed-loop control is usually used to control the temperature of the controlled object. In the temperature control system, the mathematical model of the control object (temperature) can generally be approximated as a first-order inertia link with pure hysteresis, which can be expressed by the following formula: [0003] [0004] In the formula: Kw is the gain of the object; L is the pure lag time of the object; T is the time constant of the object; S is the complex variable of Laplace transform. [0005] Most of the existing PID tuning methods adopt the bit type (On-Off) oscillation method, and the tuning process is as follows: figure 1 As shown, the temperature of the controlled object fluc...
