This paper is a theoretical and a numerical investigation of the stability ofa tip-cantilever system used in Non-Contact Atomic Force Microscopy (NC-AFM)when it oscillates close to a surface. No additional dissipative force isconsidered. The theoretical approach is based on a variationnal methodexploiting a coarse grained operation that gives the temporal dependence of thenonlinear coupled equations of motion in amplitude and phase of the oscillator.Stability criterions for the resonance peak are deduced and predict a stablebehavior of the oscillator in the vicinity of the resonance. The numericalapproach is based on results obtained with a virtual NC-AFM developped in ourgroup. The effect of the size of the stable domain in phase is investigated.These results are in particularly good agreement with the theoreticalpredictions. Also they show the influence of the phase shifter in the feedbackloop and the way it can affect the damping signal
