Design of a Data-Based Self-Tuning PID Controller

摘要

In this paper, a new design scheme of PID controllers using the DB modeling method has been proposed. Many PID controller design schemes using NNs and GAs have been proposed for nonlinear systems up to now. In employing these scheme for real systems, however, it is a serious problem that the learning cost becomes considerably large. On the other hand, according to the proposed method, such computational burdens can be effectively reduced using the algorithm for removing the redundant data. In addition, the effectiveness of the proposed method have been verified by a numerical simulation example. The application of the newly proposed scheme for real systems and the extension to multivariable cases are currently under consideration.
