Prediction Servomechanisms and its Performance

Abstract

It is observed that human behavior is much more complex and reasonable than that of conventional servomechanisms, when one controls one's own action or drives an automobile. The author thinks that it is very useful for the improvement of the performance of servomechanisms to introduce such characteristics into the construction of servomechanisms. Prediction is a characteristic of the human behavior, but it is usually difficult to introduce prediction into servomechanism construction just as it is. The author introduced prediction into servomechanisms so far as servomechanisms are constructed easily. The author investigated three kinds of prediction servomechanisms ; the first is an error-prediction-servomechanism, the second is a prediction servomechanism in which manipulated variable is computed continuously, and the third is a prediction servomechanism in which the following velocity varies automatically. It is confirmed that these prediction control servomechanisms have superior performance to that of the conventional servomechanisms.
