SHIP PROPULSION CONTROL SYSTEM DESIGN AS A WAY OF TORQUE TRANSIENT RESTRICTION

In ship propulsion systems, the engine torque is through the high-flexible coupling on the main gear. The high flexibility of the coupling is demanded because of the required correct collaboration of the flexibly supported engine and the main gear. Such a system is characterized by its considerable sensitivity to the periodic, harmonic or random disturbances. Particularly dangerous are the signals created by the irregularity of the engine running. In this case, there exists the possibility of the appearance of the propulsion system resonance with some harmonic components of the periodic (or random) disturbances. From the exploitation experience, emergencies of considerable torque overshoot of the coupling or other propulsion system elements are known. It is possible to limit these torque overshoots by an appropriate ship propulsion control system design. Based on the ship propulsion system dynamic analysis, the paper deals with the control system design aimed to improve the ship power transmission dynamic characteristics.
