气动肌肉的三元素模型辨识研究
Research on identifying the three-element model for pneumatic muscle
摘要
Abstract
Based on the three-element model for pneumatic muscle (PM) proposed by Reynolds,the experiments were conducted to identify the parameters of the PM model.The experimental results demonstrate that the contractile element Fce increases linearly with the pressure P,but a piecewise linear relationship is shown between the pressure P and the spring factor K,which rises up first and then declines with respect to the consistent increase of the pressure P.Therefore,the improved segmented three-element model was used to describe the PM model.In consideration of the small effect on the output force of PM,the damping factor B was treated as a bounded function.Finally,two different sliding mode controllers were designed and the control experiments demonstrated the effectiveness of the proposed model.关键词
