抄録

In adaptive control systems, the parameters of the controller are adjusted to obtain an optimum response using some performance index and the root mean square error value criterion is widely used as the most general and powerful performance index. This paper shows a new performance index an attention being paid to the frequency of zero crossings where the error signal crosses the zero value at a specified velocity. If the value of the specified velocity is selected appropriately and if the parameter is adjusted to maximize the frequency of zero crossings in adaptive control systems, the same result is obtained as the one obtained by the root mean square error criterion. Here the theoretical treatment of this performance index and some results by analog computer are presented.
