A design of generalized minimum variance controllers using a GMDH network for nonlinear systems

This paper describes a design scheme of generalized minimum variance contro llers (GMVC) using a group method of data handling (GMDH) network for nonli near systems. Concretely, the predictive value of the output required in th e GMVC is obtained by using the GMDH which is a kind of multilayered networ ks. Since the predictive value of the output in GMVC is calculated by a non linear model which is generated by the GMDH network, one can expect, to obt ain the better control performance than that by the conventional scheme. Th e behavior of the newly proposed control scheme is evaluated on numerical e xamples.
