Due to the self-similar property of network time-delay, a delay prediction method based on fractional autoregressive integrated moving average （FRIMA） model is proposed. Then the prediction method combined with Smith predictor is applied to networked control system （NCS）. Simulation results prove that this control strategy can avoid the negative impacts of the varying network induced delay on control performances, and provide good performances and strong robustness.

Asian Simulation Conference/The 6th International conference on system Simulation and Scientific Computing

作者： SUN Jianbo, GUO Chen (school of automation and Electrical Engineering, Dalian Maritime University, Dalian, 116026)

Based on the modeling method of the co-operation between the characteristic maps and the mathematical equations, a propulsion system simulation model which includes model for large low speed two-stroke diesel engine (MAN B&W 10L90MC) and model for shaft, propeller and ship hull dynamics are proposed. To calculate propeller's characteristic, the regression functions are represented. The simulation experiments demonstrate the model can be used for engine performance prediction as well as investigate control schedules of marine propulsion system. A self-adaptive control scheme for governor which identifies system state by means of input and feedback signals and changes PID control parameters is proposed. The simulation results show that it can improve the dynamic response of the propulsion system.
