摘要
为满足快刀伺服系统的控制需要,设计了一种压电陶瓷致动器控制系统,单片机接收到计算机的控制命令后,控制D/A转换器输出相应控制电压信号,并通过高压运放PA96将该信号线性放大,实现对压电陶瓷致动器的控制。对该系统进行驱动控制实验,结果表明系统具有精度高、结构简单、功能可靠的特点。
To meet the demand of fast tool servo( FTS),a control system of piezoelectric actuator is designed.Upon receiving the control command from PC,the microcontroller sends the control signal to PA96,and the actuator is controlled by the signal amplified by PA96. The results indicate that the system has the advantages of high precision,simple structure and stable performance.
