DIRECT DIGITAL CONTROL OF A MARINE DIESEL PROPULSION PLANT

A method to control a large bore, slow speed diesel engine utilizing a digital computer has been developed. The particular engine selected for the study was of the direct drive reversing type coupled to a fixed-pitch propeller. Computer simulation was carried out on the Interdata 70 and IBM 1130 computer facilities at M.I.T. utilizing the Dynamic System Simulation Program (DYSYS) developed by the Department of Mechanical Engineering. A hardware survey covering sensors, signal processors/coverters, mini computers (process control), actuators, and display devices was conducted. From the results of this survey, equipment for control of an actual engine could be selected. A scheme for control of the engine was constructed and carried out to the logic flow diagram level. An estimate of the computer size needed to accomplish the control process was made. In addition, a brief discussion of problems associated with automation and the state of the art was also included.
