Outline of Final Research Achievements

A design method of H∞ preview control laws which address the uncertainty of previewable information is proposed. The generalized plant for the H∞ control problem includes time varying function-valued noise in the future reference signal and typical preview uncertainties are formulated in the proposed framework. Based on a function space approach, the solvability is characterized by auxiliary matrix Riccati equations, and it is shown that the controller is given by an observer-based preview control law. For evaluating the features of the resulting control systems, proposed design methods are applied to 1) load frequency control of power systems and 2) assist control of two-link manipulator systems.
