Modelling, Simulation and Optimization of the Wavemaker in a Towing Tank

摘要

The paper analyses the problem of experimental identification (frequency response), modelling and optimization of the towing tank wavemaker in the Scilab/Xcos environment. The experimental identification of the objects (the towing tank wave-maker placed in the hydrodynamic laboratory of the CTO S.A. Ship Design and Research Centre (CTO)) and the implementation of the models in the simulation environment, enable to perform: 1．tuning of the cascade PID controller (Astrom-Hagglund relay method), 2．checking the stability (Routh-Hurvitz criterion, Nyquist criterion) of the wavemaker with tuned controller, 3．evaluating the regulatory quality and simulating of work of the optimized (Ziegler-Nichols method) system of the wavemaker. The above works and the achieved results are further described and presented in the content of this paper.
