【摘要】 采用一种简单的数值积分动态建模方法建立了大惯性温度传感器的数学模型。该方法无须迭代即可直接从微分方程辨识出模型阶次和参数。实验结果表明该方法较数值微分方法所建模型准确度高、阶次低,为改善大惯性温度传感器动态特性、实现动态补偿提供了一种有效方法更多还原

【Abstract】 A model of temperature sensors with a great inertia is set up by means of a simple numerical integral method. The model’s order and parameters are estimated from the differential equation directly without iterations. The experiments show that the model’s order is lower and the precision is higher than numerical differential method. This method makes it possible for temperature sensors to improve dynamic characteristics and realize dynamic compensation.更多还原
