2. Event-Based Feedforward Control for a Drug Delivery System for Diabetes Care 時間： 4/26 (五) 09:40~10:40地點：台大電機二館105教室 講者：Prof. TzyhJong Tarn談自忠教授 Washington University, St. Louis,MissouriTsinghuaUniversity, Beijing, China Abstract Automation plays an increasingly important role in life sciences. The wide-range applications of life science automation include genomics and proteomics automation, drug delivery system automation, cell and tissue manipulation automation, and medical automation. A key component for the above automation system development is the control mechanism design. For example, controlled drug delivery systems pursue precisely drug targeting and releasing. This obviously requires advanced control instead of conventional open-loop control schemes. Cell and tissue manipulation systems demand control mechanisms that are reliable and robust for micro- and nanoscale manipulation. Surgical robots for medical automation require advanced control methods for real-time complex mechanism control. In this talk, we will present a new event-based two degree-of-freedom control method for micro-/nanoscale systems based on differential flatness. Compared with traditional time-based feedback control, the proposed method shows great potential in dealing with measurement noise and unexpected disturbances. Applications to drug delivery demonstrate the promising robustness of the approach.

3. Robust Output Synchronization of a Network of Heterogeneous Nonlinear Agents via Nonlinear Regulation Theory 時間：4/26 (五) 11:00~12:00地點：台大電機二館105教室 講者：Prof. AlbertoIsidoriUniversityofRome Abstract In this work, we consider the output synchronization problem for a network of heterogeneous diffusively-coupled nonlinear agents. Specifically, we show how the (non-identical) agents can be controlled in such a way that their outputs asymptotically track the output of a prescribed nonlinear exosystem. The problem is solved in two steps. In the first step, the problem of achieving consensus among (identical) nonlinear reference generators is addressed. In this respect, it is shown how the techniques recently developed to solve the consensus problem among linear agents can be extended to agents modeled by nonlinear $n$-dimensional differential equations, under the assumption that the communication graph is connected. In the second step, the theory of nonlinear output regulation is applied in a decentralized control mode, to force the output of each agent of the network to robustly track the (synchronized) output of a local reference model.
