FSI is very important in engineering because it often affects safety and life time of structures. Among various types of FSI analysis algorithms, we have being studying partitioned coupling algorithms [1-4]. We are interested in controlling such FSI phenomena with active control. There are several experimental studies [5, 6]. In this study, we perform numerical simulations of FSI considering active control, taking the two-dimensional flow-induced vibration of a thin plate attached to a square column as an example. Here, the vibration is to be controlled by setting sensors and actuators on the plate and building feedback control. When introducing active control to the partitioned coupled FSI analysis, the analysis sometimes becomes unstable and fails. In this study, we focus on studying a stability condition of FSI analysis considering active control. By changing control algorithms and the placement of sensor and actuator, we find the condition which makes the analysis unstable, and then discuss how to enhance the stability of the FSI analysis considering active control.
