Integrated simulation framework for crash back operation

Abstract

We present a comparison of performance of an all-electric-ship (AES) simulator using two different approaches to control the induction machine in forward as well as in cash astern operations. The first approach uses a constant-slip control while the second uses direct-torque control. We also investigate the use of proper breaking resistors required for minimal power dissipation during the crash astern operation. The AES simulator describes a medium voltage DC system (MVDC) for the USS DDG-51 Arleigh Burke-Class destroyer.
