Abstract EN
The neurophysiological studies of animals locomotion have verified that the fundamental rhythmic movements of animals are generated by the central pattern generator (CPG).
Many CPG models have been proposed by scientific researchers.
In this paper, a modified CPG model whose output function is sin ( x ) is presented.
The paper proves that the modified model has stable periodic solution and characteristics of the rhythmic movement using the Lyapunov judgement theorem and the phase diagram.
A modified locomotion model is established in which the credit-assignment cerebellar model articulation controller (CA-CMAC) algorithm is used to realize the pattern mapping between the CPG output and the musculoskeletal system.
And a seven-link biped robot is employed to simulate cyclic walking gait in order to test the validity of the locomotion model.
The main findings include the following.
(1) The modified CPG model can generate spontaneous oscillations which correspond to biological signals.
(2) The analysis of the modified locomotion model reveals that the CA-CMAC algorithm can be used to realize the pattern mapping between the CPG output and the musculoskeletal system.
