Definitions

  • the number of times of measurement is half as compared with the case where both the PI control system and the IP control system are actually constructed and the time response is measured, so that the work efficiency can be improved.
  • the time t becomes a steady state when the natural period of the control system is about 3 to 5 times the natural period, and the integrated value is expressed by Eqs. (27), (29), (31), (33), and (35). Since these values converge, the values of a, Ti, T, and ⁇ in these equations are also known, so that the value of D's identification value D can be calculated from them.
  • the value of D ' is the coefficient (gain) of the viscous friction compensator in Fig. 1. This is shown in Fig. 11, Fig. 12, and Fig. 13, which are set as shown in Fig. 11. Then, it is apparent that the viscous friction D has finally disappeared as shown in FIG. 13 due to the known deformation of FIG.

Abstract

Méthode et appareil permettant de déterminer avec exactitude les caractéristiques d'un système régulé, comme l'inertie et le coefficient de frottement visqueux d'un dispositif mécanique pourvu d'un moteur électrique. Dans ce système régulé, différentes sortes de systèmes de régulation sont installées afin de mesurer le temps de réponse. En fonction des écarts entre les résultats de mesure, on détermine les caractéristiques du système régulé.
