摘　　要：为了满足织机的高速化和织造品种的多样化,对送经机构提出了更高的要求,需要准确控制送经机构的运动。而送经机构是一个典型的复杂、联动、时变、非线性、强干扰送经系统,传统的PID调节器不能取得令人满意的效果。针对传统的PID控制算法存在的缺陷,设计了一种Fuzzy-PID复合控制算法,并应用该算法面向SAURER400织机送经系统在MatLab中的Simulink进行仿真。结果表明,Fuzzy-PID复合控制仿真曲线在响应时间和超调方面优于PID控制曲线。该控制方法在电子送经系统中有着广泛的应用前景。In order to meet the demands of high speed weaving and diversified varieties of fabric, the let-off motion must be controlled accurately since electronic let-off system of loom has faced some new requirements. The traditional PID controller can not meet the requirements because of its typical complicated, tandem driving, time changing and non-liner winding system. Targeting the shortcomings of the traditional PID controller in loom electronic let-off and take-up motion control, a Fuzzy-PID tension controller is proposed for effective settlement of the problems of dynamic change of the non-liner system. Simulation by Simulink of MatLab is carried out on the basis of SAURER400 loom. The simulation experimental results indicate that the parameters of Fuzzy-PID are better than those of routine PID. This control method has good application potential for electronic let-off system.
