在这篇文章中，我们首先回顾LuGre模型的性质，包括零滑移位移，不变性和被动性。扩展到包括速度相关的微阻尼进行了讨论。由此产生的模型，然后用于分析粘滑运动。分析表明，由LuGre模型建模的粘滑运动是一个刚性系统，在粘滑模式下具有不同的行为，并且在这些模式之间具有戏剧性的转变。沿着速率依赖的概念，讨论了极限环对参数的依赖性。
In this article we first review properties of the LuGre model, including zero-slip displacement, invariance, and passivity. An extension to include velocity-dependent microdamping is also discussed. The resulting model is then used to analyze stick-slip motion. The analysis shows that stick-slip motion modeled by the LuGre model is a stiff system with different behavior in the stick and slip modes as well as dramatic transitions between these modes. The dependence of limit cycles on parameters is discussed along with the notion of rate dependence.
