Aiming at the complexity of mechanical devices and the polytrope of operating conditions for marine propulsion plant, the modeling and simulation of propeller and dull system are investigated based on MATLAB/Simulink. The simulation model of propeller and dull system is constructed in which the Chebyshev fit expression across four quadrants is given for the propeller. So it becomes practical to express static and dynamic properties of propeller and dull system. A luxury cruises fitted on two engines and two fixed pitch propellers is considered to perform simulation tests. The actual navigation conditions of marine propulsion plant, including starting, parking and reversing etc, are taken into account. The simulation results analysis illustrates the correctness and validity of modeling and simulation for propeller and dull system. Thus provides a new method for the optimization and design of marine propulsion plant.

Modeling and simulation of a grid-connected photovoltaic system (GCPS) is addressed in this paper to analyze its control performance and dynamics under changing irradiation. A circuit model of solar array considering irradiation is used to simulate its inherent characteristics and realized by a controlled current source. The controls of the GCPS and its electrical circuits are represented by user-defined and built-in components. The dynamic of the system in normal and fault conditions are dominated by its power controller and a method to set PI controller’s parameters is proposed in this paper. The model has been implemented on DIgSILENT. Simulation results are presented and compared with experiment waves to validate that proposed simulation model is effective for evaluation of the GCPS.

Kinematics Simulation

Parallel robots are widely used in the manufacturing industry. In this paper, a planar 3-RRR parallel robot is studied. The inverse kinematics mathematical model is established for this kind of mechanism. Furthermore, a physical simulation model is established by virtue of MATLAB/SimMechanics and a relevant inverse kinematics simulation is implemented at the assumption of known conditions of the end-effector of robot. Through inverse kinematics simulation, the motion rules of driving parts of the planar 3-RRR parallel robot are obtained, and visualization of simulation process is realized in the system. The simulation results show that this method is much more effective and convenient when a certain simulation is implemented for the parallel mechanisms. Meanwhile, it provides a theoretical foundation and a better analytical approach of simulation for the controller design and further analysis of complex multi-linkage mechanisms in the future.
