ジャーナル フリーA method for identification of a linear time invariant system is proposed which is based on the error-correcting training procedure in learning machines, and is referred to as “learning identification”.
1) Being applicable to cases where the input signal for the system identified is random and nonstationary, the method has the advantage of not disturbing the normal operation of the system significantly.
2) Since application of the method reguires only a short time, the method can be used to identify linear quasi-time-invariant systems in which some parameters vary relatively slowly in comparison with the time reguired for identification, and noise disturbances will be eliminated by means of the moving-average method, especially if the “repeating method” of the learning identification is employed. Computer simulation of the method was carried out and periods of time required for identification were obtained for various cases. Some modifications of the method-“quantizing method” and “repeating method” of the learning identification-were also investigated together with their computer simulations, and a brief account is presented to the identification of multi-dimensional linear systems.抄録全体を表示PDF形式でダウンロード (979K) -

ジャーナル フリーWith the recent progress of computer-controlled systems, there is an increasing recognition and demand for nondestructive-readout analog memory elements which play an essential function in combining a computer and a controlled process. For use in control systems, basic requirements for such elements are that not only nondestructive-readout is possible, but that contents should not be subject to appreciable variation for long period under normal operation or even when there is an emergent cut-off of electrical sources.
In view of performance and economy, a Transfluxer, a multihcle magnetic core with rectangular B-H characteristic can be used to meet specifications.
While the principle of Transfluxer itself is not new, several new ideas have been incorporated to develop a practical device using Transfluxers.
For example, high accuracy has been attained by the method of sampling and integration in feedback setting. An effective method has been developed to give a suitable bias to a two-hole Transfluxer, thereby monotoneously decresing writing characteristic for feedback setting is obtained.
The following results were obtained:
The range of memory is from -10 volt to +10 volt. The accuracy is that 2σ is less than 0.3% by the setting time of 63 milli-sec., and 0.1% by 200 milli-sec, immediately after setting. The drift after setting and the error after restoration of the damage in electrical source are both small from practical point of view.抄録全体を表示PDF形式でダウンロード (1042K) -
