【Abstract】 Abstract \ \ A temperature controller, which is based on numeric PID computational method, is developed in physics experiments at low temperature. The fluctuation of temperature can be controlled less than ±2mK over the temperature range from 4.2 to 300K. This computer based temperature controller has the advantage of robotization, high stability, credibility and low cost.更多还原
