SYNTHESIS OF A LINEAR QUICKENED DEPTH CONTROL SYSTEM FOR SUBMARINE APPLICATION
Abstract
This report describes a quickening system for manual control of a submarine in the longi tudinal mode. The synthesis is based on a modification of the automatic control system described in Electric Boat report number C417 62-019, entitled 'Synthesis of a Control System for Automatic Maneuvering of Submarines.' The quickening system of this report differs from earlier systems in that simpler expressions are used in computing quickened depth and a linear rather than a non-linear controller is used. Evaluation of the linear quickening system was performed on both the analog and the digital com puters. It was found that depth changes could be performed by untrained individuals without difficulty. The control stick was first placed at the maximum position and then gradually brought to the center position. No stick re versal was required to achieve the ordered depth change. The system has provision for automatic limiting of pitch angle to a desired maximum which is preset by the operator prior to the maneuver. The mathematical theory utilized in the development of the system is described, and the results of computer runs are graphically presented and discussed. (Author)
