Embodiment
[0052] Embodiment: A method for automatically adjusting the excitation voltage of an electric vibrating table
[0053] Assuming that the system is running at full thrust, the rated current value of the moving coil I 2 Is 1000A; rated excitation output voltage V 2 It is 100V; the adjustment coefficient δ is selected as 0.1.
[0054] Such as figure 2 As shown, the excitation voltage automatic adjustment system of the electric vibrating table is mainly composed of a current detection circuit, a control circuit and an excitation voltage adjustment circuit. Among them, the control circuit and the excitation voltage adjustment circuit form a closed-loop control adjustment. In addition, the acceleration measurement sensor, controller and power amplifier constitute a closed-loop control system that automatically increases the moving coil current.
[0055] The method for automatically adjusting the excitation voltage of the present invention is as follows:
[0056] (1) After the t...
