Abstract : Renewal process theory is used to describe the behavior of an nth order synchronous control system in which the nonlinearity is periodic (PLLtype) or a nonperiodic (DLLtype). It is shown that the stationary pdf, the mean time between two cycle slips and the average number of cycles slipped to the right and to the left can be obtained by solving a single FokkerPlanck equation of the renewal process. The renewal process approach is compared with the socalled 'periodic extension' (PE) appraoch introduced by Lindsey. It is shown that the pdf obtained via the renewal process approach can be reduced to agree with the PE solution for a first order loop only. In the general case of an nth order system, however, the two approaches lead to a different set of differential equations. In fact, it is shown that the approach based upon renewal process theory yields more information about the steadystate behavior of the system than does the PE solution. (Author)
