|
摘要
超声辅助磨削要求超声电源具有稳定的高频输出特性及反应迅速的实时跟踪特性。针对传统超声电源工作频率低、输出功率低、跟踪速度慢等问题,利用STM32F103VET6控制器和直接数字频率合成(direct digital synthesize,DDS)技术,设计并实现专用于超声辅助磨削的具有高频率、高功率和高稳定性的超声电源系统,并采用基于模糊PID(proportion,integral,differential)控制器的频率自动跟踪方法,实现快速准确地频率自动跟踪。使用所设计的超声电源进行电学性能测试及超声辅助磨削加工验证试验,结果表明:所研制的超声辅助磨削专用电源在难加工材料磨削加工中运行良好。
Ultrasonic assisted grinding has special requirements on its generator,such as stable and high frequency output and rapid response to real-time tracing.To solve the problems of low working frequency,low output power and slow tracing speed of traditional generator,a new type of generator for ultrasonic system is designed using STM32 controller and DDS(direct digital synthesize)technology.An automatic frequencytracing method based on fuzzy PID(proportion,integral,differential)controller is proposed,which works fast and accurate.The electrical performance test on the generator and the verification test on ultrasonic assisting grinding system are carried out.It can be concluded that the developed special generator runs well in the ultrasonic assisted grinding of hard-to-machine materials.
