The invention discloses a micro-dynamic accurate regulation control system which comprises a micro-dynamic device and a micro-dynamic control system. The micro-dynamic device comprises a magnetic circuit I composed of a giant magnetostrictive sheet, a permanent magnet, a static yoke I and a static yoke II, and a magnetic circuit II composed of a permanent magnet, a static yoke I, a static yoke II and a movable yoke. An air gap is formed in the magnetic circuit II. The magnetic circuit I and the magnetic circuit II are respectively provided with a magnetism regulation device. A piezoelectric ceramic sheet is arranged on the giant magnetostrictive sheet of the magnetic circuit I. The movable yoke of the magnetic circuit II is fixed through a ball screw lifting table driven by a stepping motor. The micro-dynamic control system comprises a sensor set, a signal amplifier, a signal comprehensive analysis controller, a computer, a signal generator, a power amplifier, a digital-to-analog converter and a driving power source, wherein the signal amplifier, the signal comprehensive analysis controller, the computer, the signal generator, the power amplifier, the digital-to-analog converter and the driving power source are sequentially in signal connection. The signal amplifier is connected with the sensor set. The driving power source is electrically connected with the piezoelectric ceramic sheet. The signal comprehensive analysis controller is connected with the stepping motor through a stepping motor driver.
