Properties of Optimal Preview Servomechanism

Abstract

This paper describes some properties and a simplified designing method of the optimal preview servomechanism which was proposed before by the authers. The contents are as follows.
(1) So as to abbreviate the designing time of the preview control coefficient matrix, the algebraic equations are derived.
(2) The relation between the length of preview informations and the optimal value of performance index used for designing the control system is clarified.
(3) It is pointed out that the optimal preview servomechanism involves the PID type one proposed by M. Tomizuka, et al..
