As Assessment of Slice Ship Control System Performance
Abstract
This report summarizes the effort to review existing documentation and at-sea test results and assess performance of the SLICE ship control system. At-sea data taken by NSWC-Carderock, Lockheed Martin and documentation provided by Lockheed Martin provided the baseline information to conduct the assessment. The assessment focused on the SLICE ship control hardware and software including: the control surfaces; actuation system; motion sensors; control computer and control algorithms. Seakeeping performance improvement with ride control was not demonstrated during NSWC at-sea testing. Lack of recording of the position command signals to the control surfaces prevented a detailed analysis control surface actuator performance. Analysis of selected test runs from the Lockheed-Martin at-sea testing effort identified some problem areas as detailed in this report.
