Microinjection positioning control system based on piezoelectric driving

The utility model discloses a micro-injection positioning control system based on piezoelectric driving. The micro-injection positioning control system is composed of a piezoelectric driving micro-positioning table, a control module, an acquisition module and a signal output module. Real-time displacement of a probe of the piezoelectric driving micro-positioning table is measured through the laser sensor and transmitted to the data acquisition part of the control system, a control signal is calculated through the control part and transmitted to the signal output part, and the data acquisition board card identifies and outputs the signal and sends the signal to the piezoelectric driving micro-positioning table through the power amplifier. The control system provided by the utility model has the advantages of integration, convenience in realization, high-precision control and the like, can realize full-closed-loop on-line control of various piezoelectric driving micro-positioning tables, and has potential appli
