Friction Induced Limit Cycling: Hunting R.H.A.Hensen
نویسنده
چکیده
In this paper friction induced limit cycles are predicted for a simple motion system of a single motor-driven inertia subjected to friction and a PID-controlled regulator task. The two friction models used, i.e., (i) the dynamic LuGre friction model and (ii) the static Switch friction model, are compared with respect to the so-called hunting phenomenon. Analysis tools originating from the field of nonlinear dynamics will be used to investigate the friction induced limit cycles. For a varying controller gain, stable and unstable periodic solutions are computed numerically which, together with the stability analysis of the closed-loop fixed points, result in a bifurcation diagram. For both friction models, the bifurcation analysis indicates the disappearance of the hunting behaviour for controller gains larger than the gain corresponding to the cyclic fold bifurcation point.

متن کاملExperimental results on output-feedback control of a nonsmooth rotor dynamic system
An experimental implementation of an output-feedback controller on a rotor dynamic system with set-valued friction is presented. The system exhibits coexisting stable/unstable equilibria and undesired friction-induced limit cycles. In the system, the friction and actuation are non-collocated, which prevents the application of standard friction compensation techniques. Therefore, an outputfeedba...
متن کاملAnalysis of Friction Compensation Effects in Controlled Mechanical Systems
In this paper, the effects of friction compensation, including exact compensation, undercompensation and overcompensation, in PD controlled 1DOF mechanical systems are investigated. The friction force that is acting on the mechanical system and the friction compensation term in the feedback loop are described by a class of discontinuous friction models consisting of static, Coulomb and viscous ...

Abstract This paper presents an investigation on bifurcation of railway bogie behavior in the presence of nonlinearities which are yaw damping forces in longitudinal suspension system and the friction creepage model of thewheel/rail contact including clearance...
متن کاملEffects of the longitudinal and lateral axlebox clearance on hunting, curving and wear behavior of the three piece bogies
Three piece bogies are widely in use by the freight railway services throughout the world. In comparison with the other freight bogies they cost less and are easier to maintain. However, they do not exhibit favorable curving behavior. Amongst the methods to improve the bogie performance is the proposal to introduce lateral clearance in the bogies’ axleboxs. In the case of the three piece bogies...
