Abstract

The dynamic response of a cylinder drive is considerably influenced by the mechanical damping at the load. This paper discusses the use of acceleration and pressure transducer signals to introduce active damping into drives where the load mass is supported on anti-friction bearings, i.e. where the inherent mechanical damping is a minimum. The analysis is based on the use of a linearized model. The significance of the model and the system analysis is substantiated by the results of experiments carried out to assess the merits of these forms of minor loop compensation.
