Abstract

Several methods of a controller design for a feedback control system using one-time experimental data have been proposed. However, it is difficult for the conventional methods to design a controller from data with noise and from desired I/O signals for a feedback system directly. Here, this paper proposes a method that removes a noise of data by B-spline fitting w ith binary division. A controller is designed by using the linear transform of a controlled plant. To realize the transform, the method needs a key technique to smooth experimental data. The paper describes a technique for data smoothing using B-spline function for Data Conversion Method (DCM) and the controller design. As a result, this paper shows that a designed controller can achieve the desired feedback responses for several plants.
