CONTROL STRATEGY FOR MULTI STATE PRESS SYSTEM USING REAL TIME EMITTANCE MEASUREMENT

Abstract

The closed loop Analysis and Diagnostics of industrial Electrical drives has received an intense
amount of research interest during the recent years. Reducing Maintenance Costs is the main Objective of
Electrical Drive Manufacturers and Operators. A new monitoring technique called real time emittance
measurement Technique is proposed for closed loop operations and to detect the faults occurring in the main
line manufacturing unit. This technique has been tested through the simulation of an IM using a closed loop
operation model. In order to demonstrate the capability of the proposed tool for robust condition monitoring,
these simulations are complemented by the experimental results obtained from faults occurred in the chain
manufacturing industry, powered from sinusoidal supply voltages. The former technique, based on open loop
control does not identify faults near the sidebands which troubles the manufacturing and causes unscheduled
downtimes. The results obtained by the Faulty Operation Strategy method show the merits of the proposed
approach for the detection of faults. The new technique for the diagnosis identifies the faults around the
sideband frequencies around the main frequency components of a line manufacturing unit .This technique also
detects typical problems such as belt Damage, Belt Looseness, Gear tooth Damage.
