Abstract(in English) | We propose a method to estimate unknown parameters of coupled dynamical systems from observed data using a merging particle filter. As an example, we consider a mathematical model of CPG (Central Pattern Generator) that generates rhythmic gait patterns in the spinal cord of animals. Using the data obtained by simulating a coupled-oscillator model proposed by Golubitsky et al., we estimate the parameters of the model. We confirmed that the merging particle filter can successfully estimate most of the parameters of representative gate patterns. In some cases, different parameter sets that generate the same gait patterns were found. We also discuss that some of the parameters can be more easily estimated when the system noise is stronger. |
