使用直接驱动的直线电机,能把控制对象和电机做成一体化结构,在精度、快速性、耐久性等方面具有明显的优势。用DSP作为控制器对纺织机械电子横移系统的电子凸轮机构进行实用设计,采用电流环、速度环的双闭环控制电极位置和速度,用先进的SVPWM控制算法对参数进行反复优化,使伺服系统达到更好的效果和更高的性价比。 The use of direct drive linear motor, the control object and the motor can be made into an integrated structure, in terms of accuracy, rapidity, durability and other obvious advantages. Using DSP as the controller, the electronic cam mechanism of electronic mechanical shift system of textile machinery is designed. The position and velocity of the electrode are controlled by the double loop of current loop and speed loop. The parameters are repeatedly optimized by the advanced SVPWM control algorithm, Achieve better results and higher cost.
