【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 proportional synchronous pressure relief circuit is designed for the synchronous pressure relief of the vertical hydraulic cylinder when the docking locking mechanism of the ship lift is out of operation. The mathematical model of the proportional pressure relief circuit is established, and the self-tuning PI control strategy based on the feedforward of the fuzzy control belt is designed in combination with the characteristic of the system working point in the process of pressure relief. The response speed of the system is improved by the feed-forward, and the robustness of the system is improved by the fuzzy control. The effectiveness of the electro-hydraulic proportional pressure relief circuit and the control strategy of the butt-locking mechanism is verified by the method of joint simulation of AMESim and MATLAB.
