The generalized Maxwell-slip model: a novel model for friction Simulation and compensation
TL;DR: A novel, multistate friction model is presented, which is obtained from the Maxwell-slip model by replacing the usual Coulomb law at slip by a rate-state law.
Journal ArticleDOI
Single state elastoplastic friction models
TL;DR: A new class of single state models is defined in which presliding is elastoplastic: under loading, frictional displacement is first purely elastic and then transitions to plastic, to substantially reduce drift while preserving the favorable properties of existing models.

Trajectory planning and feedforward design for electromechanical motion systems
TL;DR: In this paper, the authors considered trajectory planning with given design constraints and design of a feedforward controller for single-axis motion control and showed that the fourth-order trajectory planning is time-optimal in most relevant cases.
Trajectory planning and feedforward design for electromechanical motion systems
TL;DR: Simulations and hardware-in-the-loop experiments show superior effectiveness of fourth- order feedforward in comparison with lower-order feedforward.
