Abstract | Links | BibTeX | Tags: Blended dynamics, Heterogeneous multi-agents, Sampled data system @inproceedings{NamKimParkShim20, In this paper, we address the problem of synchronization among heterogeneous agents in a sampled-data setting. The key observation is that the sample-and-hold process introduces additional node-wise weights on the Laplacian matrix in the discrete-time domain. We then show that in the sampled-data setting, all of the agents' states approach the state of the so-called weighted averaged dynamics, an auxiliary dynamics that represents the collective behavior of heterogeneous agents when they are synchronized. In addition, admissible ranges of the sampling period and the diffusive coupling gain are computed, with which the consensus among the agents is achieved in a practical sense. |

Gyunghoon Park / Hyungbo Shim / Kyungchul Kong Can Continuous-time Disturbance be Represented by Sampled Input Disturbance? Proceedings Article In: Proc. of 2016 16th International Conference on Control, Automation and Systems, pp. 1261-1266, IEEE, Gyeongju, Korea, 2016. Abstract | Links | BibTeX | Tags: Continuous-time system, Sampled data system, Stability @inproceedings{ParkShimKong16, Abstract: In this paper, we study whether any continuous-time disturbance to a continuous-time plant can be equivalently represented by a sampled input disturbance to a sampled-data model. With the help of the sampled-data system theory, we show that such equivalent sampled disturbance exists for almost sampling period and even for mismatched continous-time disturbances. Moreover, it is also discussed that whether the equivalent sampled disturbance is bounded significantly depends on the zeros of the sampled-data system. Simulation results verify the validity of the stability analysis. |
