双参数摆的自适应耦合同步

ue to potential application in wave energy collection, dual parametrical pendulum attracts attention in the community of dynamical system and control. The conventionl research about dual parametrical pendulum is based on periodical excitations, however, the wave excitation is non-periodical, as a result, conventional research results can not be used for wave energy collection applications. In order to improve the efficiency of wave energy collection, the dual parametrical pendulum is expected to be in rotating state, at the same time, two pendulums are expected to be anti-direction synchronization to avoid horizental oscillation. Because the input exication period is unknown, a piece wise adaptive coupling synchronization method is used to implement a kind of master-slave anti-direction synchronization. At the same time, the master pendulum is controlled using adaptive time delay feedback control to sustain the rotation itself. Simulation results show the effectiveness of the method.
