Wavemaker control system for irregular developed sea waves generation

The paper presents implementation and performance of an irregular sea wavemaker system. The system is designed for the purpose of testing sea waves impact on coastal facilities. It is suitable for long-crested two-dimensional irregular sea waves generation. The control algorithm is comprised of the offline calculation of the control waveform and the real-time governing of the wave paddle. Offline algorithm is implemented on a personal computer, whereas paddle control is realized on a programmable automation controller. The paper describes the generation procedure of a stochastic waveform according to criteria set in advance, as well as the control algorithm for producing the desired waveform. Functionality of the system is validated by experiments.
