Description

technical field [0001] The present invention relates to the technical field of power digital control, in particular to a digital control device, a control method thereof, a control system, and a storage medium. Background technique [0002] With the continuous advancement of drive control technology, piezoelectric actuators have been used more and more in precision positioning and fast correction systems. Traditional piezoelectric actuators usually use an analog circuit built with an operational amplifier for closed-loop control. This analog control method has a large closed-loop bandwidth and high anti-interference ability, which will make the closed-loop parameter setting of the control system more complicated, and then the system It is difficult to achieve the optimal closed-loop control effect. Therefore, a digital controller emerges as the times require. The digital controller can easily adjust the closed-loop parameters of the control system, so as to achieve a relati...
