摘　　要：影响系数法及自动寻优控制是目前广泛研究的平衡头控制方法,但其存在平衡效率低且平衡精度不足等问题,在实际应用中存在较大局限性。针对上述问题,设计了一种基于极坐标式的质量块型平衡头,采用蜗杆蜗轮减速装置带动质量块实现准确定位,并提出了一种基于模糊PID的自适应控制策略,最后通过实验验证并与传统基于影响系数的控制策略进行对比,结果表明该控制策略较传统的影响系数法及自动寻优方法具有较高的平衡效率和平衡精度。Influence coefficient method and automatic optimization control strategy are extensive research method in the balancing head currently,but because of the low balancing efficiency and balancing accuracy,there are many limitations in practical application. Aiming at the problems above,a balancing head of polar coordinate type with two mass blocks is designed in this paper. Worm and gear assembly is used to make the mass block run to the proper position,and a self-satisfaction control based on fuzzy-PID is introduced to solve the problem. The experimental verification shows the effectiveness of the design,and the strategy has higher balancing efficiency and accuracy compared with the traditional influence coefficient method and automatic control strategy.
