On Central Pattern Generator of Biological Motor System

This paper presents theoretical results of the neural control mechanism existed in the spinal cord, central pattern generator (CPG), which has the ability to provide rhythmic movement patterns for the invertebrate and vertebrate. It is known that although CPG is verified by biological methods, it still lacks a complete theoretical investigation. The theoretical analysis about CPG from engineering perspective such as parameter selection and conditions of stable oscillation will strengthen the foundation of CPG theory, and it will significantly enhance the effective application of CPG into motor control systems.
