Friction Analysis Based on Integral Quadratic Constraints

Rantzer, Anders LU (2001) In International Journal of Robust and Nonlinear Control 11(7). p.645-652
Abstract
Passivity arguments have long been used in the analysis of systems with friction. This paper proves a new set of integral quadratic constraints, which reduces the conservatism of such methods. The result is used to derive a quantitative bound on the amount of integrator leakage that is needed to remove stiction-induced oscillations in a servo system.

Finally, an incremental version of the circle criterion is used to study the existence of subharmonics due to friction in a system subject to externally forced oscillations.
