摘要
依据能量守恒定理,对喷气织造过程中的纬纱张力峰值进行公式推导,指出降低纬纱张力峰值的途径是降低纬纱制动时的纬纱速度。在此基础上,给出纬纱张力控制器的实现方法。研究了一种新颖的纬纱张力控制方法,该方法引入纬纱到达时间的线性预测,能够在降低纬纱张力的同时,调整纬纱到达时间的不匀,从而稳定纬纱飞行状态。结合现有的纬纱到达时间的控制方法,构成较完整的引纬控制策略。
According as energy conservation principle, the formula of weft tension peak value during air-jet weaving was deduced. It points out that the way to decrease the peak value is to decrease the weft speed at weft braking. Based on this, the method of weft tension controller was introduced. It has developed a new method to controlling weft tension. The linear prediction will be used in the method. It decreases the peak value and consoles the coefficient of mean deviation of arriving time, thus leveling off the flight state of weft and improving production efficiency. It constitutes an integral weft control strategy when coupled with the existing control method of weft arriving time.
