The invention belongs to the technical field of electro-hydraulic servo control of composite plate rolling forming, and particularly relates to a position compensation control method for a hydraulic servo system of a corrugated roller rolling mill. In the process of carrying out composite plate production by using the corrugated roller rolling mill, a rodless cavity of a servo hydraulic cylinder is certainly provided with pressure fluctuation and impact, in order to reduce the pressure fluctuation and impact of the rodless cavity of the servo hydraulic cylinder in the rolling process and to achieve the accurate control on the rolling process of a composite plate, pressure fluctuation signals need to be embedded into a position closed-loop control process in real time through a position compensation controller in a position compensation mode, so that the control performance of the hydraulic system is improved; and the position compensation controller can judge whether position compensation is carried out on the hydraulic servo system of the corrugated roller rolling mill or not. According to the position compensation control method for the hydraulic servo system of the corrugated roller rolling mill, the effects of being simple and easy to understand are achieved, the control performance of the hydraulic system of the corrugated roller rolling mill is improved, a new idea is provided for the control method of the hydraulic servo system of the corrugated roller rolling mill, and the guiding significance for reality production is achieved.
Description
technical field [0001] The invention belongs to the technical field of electro-hydraulic servo control for rolling forming of composite plates, and in particular relates to a position compensation control method for a hydraulic servo system of a corrugated rolling mill. Background technique [0002] The traditional composite plate rolling production process is that the upper and lower work rolls of the rolling mill are respectively rolled with flat rolls in contact with the two metals, so as to realize the horizontal and vertical extension of the two metals. However, in actual production, due to the upper and lower two The elongation of different metals is different, it is easy to cause large curvature warping of the metal, and continuous production cannot be performed. Composite plate corrugated roll rolling technology is a transformative and subversive technology, which can promote better metallurgical bonding of two materials, improve bonding strength, and realize continu...
