Abstract

With the use of simulation models, predicting and optimising the correct dynamic behaviour and parameters of a propulsion system of a ship can be performed cheap and safe. However, capturing the right dynamic behaviour is very difficult. Besides, building simulation models and determining the correct parameters is a time consuming process. With system identification, in- and output data of a controlled test are used to identify the parameters of the created grey box model structure, which reflects the underlying physical laws. A so called "fingerprint" is generated that imitates the behaviour of the system. The first attempt of system identification of a full-scale propulsion system showed promising results but asked for further research. This thesis further investigates if system identification is a suitable method to obtain the dynamic model- behaviour and parameters of a full-scale propulsion system in a short time, with the use of controlled tests.
