| Zusammenfassung: | The invention provides a method and device for improving synchronism of a hydraulic cylinder and an electric cylinder, and the method comprises the steps: obtaining an actual position time domain signal of the hydraulic cylinder through real-time feedback of a linear displacement sensor in a sampling time period, and installing the linear displacement sensor on the hydraulic cylinder; an actual position time domain signal of the electric cylinder is obtained through real-time feedback of a motor encoder; respectively calculating real-time precision errors of the actual position time-domain signal of the hydraulic cylinder and the actual position time-domain signal of the electric cylinder; hydraulic cylinder time delay and electric cylinder time delay are obtained according to the real-time precision error; time compensation is conducted on the control system according to the hydraulic cylinder time delay and the electric cylinder time delay, and the synchronism of the hydraulic cylinder and the electric cyli |
