【摘要】 针对冲击载荷下的磁流变阻尼器,提出了以"平台效应"为后坐缓冲的控制目标,分析了延时控制策略在整个后坐过程中的重要性,以后坐速度和后坐位移为反馈量,设计了延时模糊自适应控制和延时模糊PID控制策略。对所设计的阻尼器进行冲击台架实验,通过比较阻尼力峰值和后坐平台宽度,分析了这两种控制策略的优缺点,其中以模糊PID控制效果最优。更多还原

【Abstract】 According to Magneto-rheological(MR)damper under impact load, platform effect using as control objective of recoil mitigation is be proposed. The delay control strategy should be emphasized in the whole recoil process.Using the recoil velocity and recoil stoke as feedback quantity, the delay fuzzy adaptive control algorithm and the delay fuzzy PID control algorithm are designed. The impact bench test for the special designed MR damper is done. Comparing the peak of damping force and its platform width, the advantages and disadvantages of each control strategy are analyzed, in which the effect of fuzzy PID control algorithm is best.更多还原
