报告摘要：
       This talk will report the recent progress of output regulation problem of an Euler-Bernoulli beam. We start with a brief introduction to output regulation problem and state the internal model principle which is the major approach solving the regulation problem in the literature. Then we discuss the output regulation of Euler-Bernoulli beam system which is not a linear regular system. To solve the difficultly of using the internal model principle of the infinite dimensional system assumed to be a linear regular system, we propose an adaptive control approach by developing three auxiliary systems: the first one is used to convert the in-domain disturbance into the boundary disturbance; the second is used to make the measured error become the boundary output; the last one is used to transform the design problem of output regulation into the control design of stabilization problem which can be solved by using the existing control method. The proposed control law regulates the tracking error to zero and keeps the states bounded. This work is joint work with Wei Guo and appears in SICON.
