| Abstract: | According to the basic requirement of micro powder conveying,a multiple piezoelectric control system based on DDS technology was proposed,including the waveform storage module,the reference frequency module,a reference voltage setting module and D/A output module,etc.The system can realize the independent control and multi-channel signal output with voltage range of 0-100 V and frequency range of 0-256 Hz.Taking the hydroxyapatite and zirconium oxide powder for example,the multiplex micro powder conveying experiment was has carried out.The results show that the designed system can completely satisfy the requirements of micro powder conveying and has very high stability and reliability. |
