    摘要:

    针对升船机对接锁定机构退出工作时,竖向液压缸比例同步泄压需要,设计了电液比例同步泄压回路。建立了比例泄压回路的数学模型;结合泄压过程中系统工作点在较大范围变化的特点,设计了基于模糊控制带前馈的自整定PI控制策略,通过前馈提高系统的响应速度,通过模糊控制来提高系统的鲁棒性。采用AMESim和MATLAB联合仿真的方法,验证了对接锁定机构电液比例泄压回路及控制策略的有效性。

    Abstract:

    An electro-hydraulic propotional synchronous pressure relief system is designed to meet the requirements of vertical hydraulic cylinder at pressure relief, when the ship-lift butt-joint device is quitting working state. The synchronous pressure relief system model was built. A self-tuning Proportion Integration (PI) control strategy based on fuzzy control with feed-forward was designed, for the characteristics of changing in large range of working point in the pressure relief process, through the feed forward to improve the response speed of the system, and through the fuzzy control to improve the robustness of the system. The simulation result can verify the effectiveness of synchronous pressure relief system and the closed-loop control strategy to the pressure relief system of butt-joint device, by using AMESim and MATLAB co-simulation method.
