要約(日本語): The output feedback control which derives the semi-optimal solution which makes the minimum the cost function which assumes system noise and includes the state and the control input is proposed. The modified output feedback control which assumes system noise and output observation noise and evaluates only the state as a method of deriving the optimal solution is proposed. Considering an actual system, we think that it is not realistic to evaluate the state where it cannot observe. Moreover, although output observation noise may be removable by designing a filter, it is difficult to remove the state observation noise mixed in an internal state. We show the solvability condition of the control problem which assumes system noise and state observation noise and evaluates only the output.
