  • Patent number: 8417389
    Abstract: There is proposed a control system and the like that can realize a CPG (Central Pattern Generator) network having high controllability. A control system (CPG network) includes a plurality of oscillation control devices (CPG) and one target signal generating device (rhythm generator (RG)). Each CPG and the RG are described by the Van der Pol equation, and an amplitude and a period of an output waveform are substantially independently controlled by an external signal. In order to control a phase difference between the CPGs, the period of each CPG is temporarily controlled through connections that are only conjunctions between the each CPG and the RG.
