Towards the optimal flow control, series of techniques for fast and accurate data assimilation of flow fields are investigated and developed. Following items are studied: :(i) Acquisition of the detailed unsteady data by optical flow technique and reduced order modeling, and (ii) new method based on calculus of variation with the sub-optimal control theory. With regard to the item (i), detailed unsteady flow data is obtained and the reduced order modeling is applied for reduction of computational costs. With regard to the item (ii) the sub-optimal theory is utilized for the construction of fast and accurate data assimilation.
