Most of the previous studies on the synchronization of coupled limit-cycle systems focused on synchronization in the context of phase or frequency locking. In this letter, we study complete synchronization in coupled limit-cycle systems in terms of complete trajectory locking, by generalizing the master stability function method, which is originally developed in the study of synchronization in coupled chaotic systems. Four typical types of transverse Lyapunov exponent of standard mode, which lead to different synchronization-desynchronization patterns, are classified. In many respects, the behaviors in such coupled systems are distinct from those in coupled chaotic systems, such as the size effect and the desynchronous behavior.
