In Control designing control systems, it is important to make the exactly mathematical model of the control object. However, it is relatively difficult to obtain the mathematical model for nonlinear systems. There are few works on desinging nonlinear models. As one of them, the group method of data handling (GMDH) network has been proposed as a method to represent a nonlinear property. It is a kind of multilayered networks with a structure which is configured through training, and has a feature that the nonlinear dynamics are expressed as a mathematical model. However, since the mathematical model generated by the GMDH includes many needless terms, it becomes considerable large. In this paper, a nonlinear modeling scheme using a GMDH and two kinds of GA is proposed. According to the newly proposed scheme, necessary terms in the GMDH are choosen by using the binary-coded GA, and system parameters are adjusted by using the real-coded GA.
