Prof. Viet-Hung Vu

Canadian professional engineer and PhD in 2010 with the prestigious Canada NSERC Innovation Challenge Award. Currently, Dr. Vu is an Assistant professor at the Royal Military College of Canada and an adjunct professor at École de technologie supérieure. With the NSERC Discovery grant, he and his research team pursue innovations in robot structures’ dynamics and operational modal analysis. The approaches include both analytical modeling and experimental analysis and a hybrid of the two. Some recent findings are the linearization and symbolic implementation of dynamic equations, the times series model updating for automatic operational modal analysis, the forces identification, and the uncertainties in operational modal analysis.

Title: Flexible Robot Dynamics and Vibration: From Analytical Modeling to Experimental Modal Analysis

Abstract: Recent studies and research on the dynamics and vibration of an industry-developed flexible robot with 6 degrees of freedom are presented. The flexibility of the joints and links is considered. The nonlinear dynamics and non-stationary vibration behavior of the robot structure during a grinding application are studied in both analytical and experimental approaches. A linearization model is presented, in conjunction with a symbolic computation, allowing the direct and inverse analytical dynamics of the system in the whole workspace. In the experiments, modal testing and operational modal analysis using the autoregressive moving average models and various identification techniques reveal the true spatial dynamical properties and the updating of these parameters in non-stationary vibrations. The two approaches’ efficient performance and the matching of the analytical-experimental results promise a perspective of a hybrid modal analysis technique for flexible structures and robots under real, complex working conditions.

Title: Coordination of Drones at Scale in Smart Cities: From Distributed Optimization to Multi-agent Reinforcement Learning

Abstracts: Smart C ity applicat ions such as traffic monitoring and disaster response can be revolutionized by swarms of intelligent and cooperative drones. Drones can collect sensor data in parallel over different areas of interest and time spans within unpredictable environments. However when missions become spatio-temporally large and evolving during flying operations, recharging drones while meeting sensing requirements and battery constraints becomes a challenge. To address this timely problem we first introduce a scalable and energy-aware model for planning and coordination of drones for spatio-temporal sensing. The coordination model is built upon a decentralized multi-agent collective learning algorithm (EPOS) to ensure scalability, resilience and flexibility that existing approaches lack of. We then augment this novel approach with a multi-agent deep reinforcement learning approach to account for long-term strategic decisions made collectively by the drones to maximize the accumulated performance benefits. This allows swarms of drones to self-optimize their operations while they learn to “follow” the phenomenon they observe, e.g. traffic jams or a forest fire. Experimental and analytical results illustrate the outstanding performance of the proposed methods compared to state-of-the-art approaches, while providing a deeper understanding on coordinated mobility of drones.
