Validation of pre-sliding friction models for ultra-high precision applications

Friction is one of the main disturbances in precision positioning and, in the pre-sliding motion regime, it is characterised by an elasto- plastic nonlinear hysteretic behaviour with a marked variability. Pre-sliding friction, modelled via the state-of-the-art Generalised Maxwell Slip (GMS) and the Hsieh model (HM), is experimentally assessed in this work with the aim of developing suitable control typologies aimed at compensating its effects. The models are hence compared in terms of the complexity of identifying their parameters, simulating their dynamic responses and implementing them in real- time systems. It is thus shown that the GMS model is readily identified and comprises also the sliding motion regime, whereas HM is difficult to implement and requires a separate sliding friction model with a corresponding switching function.
