System Dynamics Optimization of the Ship Piston Compressor with Electric Drive

System dynamic simulating modelling is one of the most appropriate and successful scientific dynamics modelling method of the complex, non-linear, natural, technical and organisational systems. Investigation of behaviour dynamics of the ship/s propulsion system as one of the complex, dynamic, non-linear technical systems requires application of the most efficient modelling methods. Ship/s piston compressor and its driving electric motor, i.e. in this case, asynchronous motor shall be presented in the POWERSIM simulation language i.e. mental-verbal, structural and mathematical computing modules. System dynamic models are essentially continuous models since the realities have been demonstrated by a set of non-linear differential equation, i.e. “ equations of conditions” , however they are at the same time discrete ones because their principle time interval calculation i.e. (discretisation) sampling “ DT” is determined in full compliance with (Sampling Theorem) by Shannon and Koteljnikov.
