Abstract

Improving the dynamic performance of impact force control is one of the key factors to ensure the bonding quality in wire bonding processes of IC microelectronics products. A fuzzy active disturbance rejection control (fuzzy ADRC) method is proposed to reduce the impact force and the consequent fluctuation of the bonding head. This control method uses a fuzzy controller to automatically adjust the control parameters of the error feedback controller based on the standard ADRC. With this fuzzy ADRC control method, the overshoot of the bonding head positioning response can be effectively reduced, and the fluctuation of the impact force can be controlled within a small region. The dynamic simulation model of impact force is established, and the design process of fuzzy ADRC control strategy for bonding head servo system is described in detail. Compared with conventional PID and fuzzy PID, simulation and experimental results demonstrate that the fuzzy ADRC control method can achieve better performance in reducing the impact force overshoot and force fluctuation. Therefore, the fuzzy ADRC control method for high dynamic Z-axis motion can improve bonding quality.

基于模糊自抗扰控制器的高速焊丝机冲击力控制

提高冲击力控制的动态性能是保证IC微电子产品线接质量的关键因素之一。提出了一种模糊自抗扰控制(fuzzy自抗扰控制)方法，以减小撞击力和随之产生的焊头波动。该控制方法在标准自抗扰控制器的基础上，利用模糊控制器自动调整误差反馈控制器的控制参数。采用该模糊自抗扰控制方法，可有效减小粘接头定位响应的超调，将冲击力的波动控制在小范围内。建立了冲击力的动态仿真模型，详细描述了粘接头伺服系统模糊自抗扰控制策略的设计过程。仿真和实验结果表明，与传统PID和模糊PID相比，模糊自抗扰控制方法在减小冲击力超调和冲击力波动方面具有更好的控制效果。因此，采用模糊自抗扰控制方法对高动态z轴运动进行控制，可以提高粘接质量。
