【摘要】 智能泵源可以根据导弹飞行状态的不同,调节泵源转速和输出压力,能够有效提高液压舵机的效率。本文主要讨论泵源系统的压力控制问题,针对泵源系统的参数不确定性,设计了泵源压力的模糊滑模控制器。通过比较PID控制、滑模控制和模糊滑模控制的控制效果,实验发现模糊滑模控制既有很好的鲁棒性又能克服单纯滑模控制的抖振问题。更多还原

【Abstract】 The intelligent pumping source can greatly improves the work efficiency of hydraulic actuator by adaptively adjusting its rotational speed and output pressure.In this study the pressure control of intelligent pumping source of hydraulic actuator was emphasized,and a pressure control method based on fuzzy sliding mode control(fuzzy-SMC)was proposed to solve the parameters’ uncertainty of the pumping source system. Comparisons of three control methods among PID,SMC and fuzzy-SMC are made,and the compared results show the fuzzy-SMC has better robustness and can effectively restrain the quiver.更多还原
