Abstract:根据所研制的一种典型结构的非共振椭圆振动切削(Elliptical Vibration Cutting,EVC)装置,考虑压电叠堆在非共振EVC装置表现出来的动态迟滞特点,对静态PI迟滞模型进行分段动态化权值处理,构建动态PI迟滞模型描述非共振EVC装置各轴向输入电压与输出位移的关系。通过对迟滞模型的求逆建立非共振EVC装置的前馈控制器,为进一步提高控制系统的精度与稳定性,引入PID反馈环节,用前馈逆控制器加PID反馈的复合控制方法控制非共振EVC装置各轴向输出指定频率、幅值的正弦位移,进而使其合成的椭圆振动轨迹运动频率、轴长和倾角满足需求,实现对非共振EVC装置的控制。试验结果表明,非共振EVC装置在复合控制下能够在频率100Hz以下输出振幅、倾角可调,且运动误差低于3.5%的椭圆振动轨迹。
