摘要

Multiaxis vibration control as a means to recreate service stress in the laboratory has achieved a great deal of success in the last decade. While initial applications centered around components and assemblies requiring a relatively few number of inputs (1 to 4), current applications such as a full vehicle simulation may require 12 or more exciters. The complexity of the control process required to accurately reproduce the time history response for a full vehicle simulation often requires that an expert operator intervene to coax the system into convergence. The time spent developing a control signal for a simulation test is costly in terms of both program timing and equipment wear and tear. Often, compromises must be made due to the inability of the control system to create a fully accurate response given the available time and resources. This article discusses the development and application of a new robust control technique that decreases operator interaction while improving control accuracy.
