In this paper, we present an analytical study on the synchronization dynamics observed in unidirectionally-coupled quasiperiodically-forced systems that exhibit strange non-chaotic attractors (SNA) in their dynamics. The SNA dynamics observed in the uncoupled system is studied analytically through phase portraits and Poincare maps. A difference system is obtained by coupling the state equations of similar piecewise linear regions of the drive and the response systems. The mechanism of synchronization of the coupled system is realized through the bifurcation of the eigenvalues in one of the piecewise linear regions of the difference system. The analytical solutions obtained for the normalized state equations in each piecewise linear region of the difference system have been used to explain the synchronization dynamics through phase portraits and time-series analysis. The stability of the synchronized state is confirmed through the master stability function . An explicit analytical solution explaining the synchronization of SNAs is reported in the literature for the first time.
