The Design of a Control System for a Superimposed Frequency Fatigue Test Machine

CODEN: JTEVAB

Abstract

The conjoint action of high- and low-frequency fatigue on a test specimen has been obtained using a servohydraulic test machine. A control strategy was implemented such that only one servo-actuator was required to obtain both low- and high-frequency components. This paper describes the test rig and the decoupled automatic controller development for it.

Test results show that the decoupled strategy systhesis produces satisfactory separation of the low- and high-frequency modes of the closed-loop response.
