Stiction is stationary friction
WebOct 29, 2005 · In this paper, a framework that utilizes a stiction measure for effective stiction compensation in process control valves is proposed for the first time. The performance of a friction compensator termed the “knocker” proposed in the literature is studied. It is observed that the choice of knocker parameters has a significant influence … WebWe have studied the effect of Coulomb friction and stiction on force control with integral feedback. The force is applied through a compliant transmission by a velocity-controlled motor. Our results show that stiction can cause the applied force to enter a limit cycle. Coulomb friction can extend the system stability bounds but may lead to an input …

Definitions: Stiction: an abbreviation of “static friction” - the friction between stationary surfaces at rest, which resists them beginning to slide over one another. Friction: the resistance that one surface encounters when sliding over another. Generally speaking with suspension this refers to “dynamic friction”, ie the frictional force while …
WebFeb 7, 2013 · For general purpose, stiction can be defined as the resistance to the start of motion usually measured as the difference between the external force being applied in … WebStiction is the static friction that needs to be overcome to enable relative motion of stationary objects in contact.[1] The term is a portmanteau of the words static and friction,[2] and is perhaps also influenced by the verb to stick.
WebDec 27, 2024 · Stiction is the static friction that needs to be overcome to enable relative motion of stationary objects in contact. The term is a portmanteau of the words static … WebAfter some time in operation, wear results in friction and backlash deteriorate the control performance. Valves with a high level of static friction (stiction) generate stick–slip motion that causes the control loops to oscillate. When the stiction or backlash becomes large, the valve should, of course, be repaired or replaced.
WebSometimes the word ‘stiction’ is used in discussion of friction but its use is not preferred by the authors since many practitioners either fail to define it or use it inconsistently, or both.
