Environment for random and sinusoidal vibration test control of an inverter-fed electrodynamic shaker

In this paper, an environment for random and sinusoidal vibration test control of an inverter-fed electrodynamic shaker is presented. This set-up is particularly applied on methods for testing of mechanical components based on the ANSI/ASAE standard EP455. First, the system configuration of an inverter-fed electrodynamic shaker and a LC filter is shown, as well as, the dynamic model of the plant is found, after, the control methods are discussed. Then, the technical development of the ACPS is described. The goal of the application is achieved from a software implementation on, which executes the proposed algorithm based on a robust model reference control law (MRC) with a repetitive controller (RC). The effectiveness of the proposed control scheme is verified by measured results.
