简化模型预测方法在气流染布机温度控制中的应用

摘要

The temperature of airflow dyeing machine has a pure delay, which affects yarn quality seriously. The SM - MAC control algorithm, Simplified model, reduces the number of coefficients to simplify the calculation of the control variables. And adapts to airflow dyeing machine temperature system's characteristics - complex model and large - delay. Experiments show that the method not only guarantees the good tracking effect and exact control accuracy of the control system, but also improve the response speed of control system and the control quality.%气流染布机温度具有大纯滞后的特点,严重影响了染纱质量.采用简化模型预测方法可减少相关系数的个数,简化控制量的计算,可适用于复杂、纯滞后温度系统模型.并且通过实验表明,该方法不仅保证了控制器良好的温度跟踪效果和控制精度,而且提高了控制系统的响应速度,改善了染色质量.
