The paper proposes a novel approach to identification of continuous-time systems from sampled I/O data. The coefficients of plant transfer functions are directly identified by applying an iterative learning control which enables us to achieve perfect tracking for uncertain plants by iteration of trials. Furthermore, one way to make the method robust against(More)
A study of a non-destructive inspection system for hidden special nuclear materials in the cargo container at the sea port has been carried out under a promotion of Japan Science and Technology. This inspection system consists of an active neutron detection method for a fast screening purpose and a nuclear resonance fluorescence (NRF) method for isotope(More)
The paper proposes a new iterative learning control for a class of linear continuous-time systems, which achieves high-precision tracking for uncertain plants by iteration of trials in the presence of heavy measurement noise. The robustness against measurement noise is achieved through (i) projection of continuous-time I/O signals onto a finite dimensional(More)
— The paper is concerned with both iterative learning control (ILC) and identification of continuous-time systems based on sampled I/O data in the presence of measurement noise. First, we propose a new ILC method which achieves tracking for uncertain plants by iteration of trials. The distinguished feature of this method is that (i) the leaning law works in(More)
The whole mouth method gustatory test is a simple gustatory test. It can be applied easily, and can be used to assess overall taste which a subject is supposed to be feeling. In the present study, a new series of taste solutions for the use in the whole mouth gustatory test was prepared. In order to determine the normal range of gustation and relationships(More)
