In the present paper, the practical design method of a strongly stable system for the self-tuning control is proposed. When the system parameter changes greatly, a series compensator having unstable poles appears in a self-tuning control system frequently, even if the closed-loop system is designed to be an optimal servo system. However, the appearance of an unstable series compensator in this control system is undesirable in terms of stability. By relating the stability index of the series compensator to the significant design factor deciding control performance, the designer can easily derive very useful solution with respect to the problem of the unstable controller. In other words, the strongly stable self-tuning control system is achieved, by adjusting automatically the weight of a performance index in the optimal control on the basis of the stability index. Furthermore, the fuzzy inference is effectively introduced into this adaptive control system in order to adjust the performance weight appropriately. In addition, numerical simulation is used to prove that the proposed method provides sufficient performance regarding both tuning and control.
