Feedback control system for velocity profile employing three parallel planar jets was established. Velocity distribution was measured by an array of three hot-wire probes and jets exit velocity were manipulated by PI controller and conditioner in order to suppress fluctuation of the peak position of mean velocity distribution. Time constants of blowers output and fluid movement were investigated and performance of control was evaluated in various time scales. Suppression of the peak position fluctuation was realized compared to that without control, and the system became robust against the cross-flow disturbance.
