Abstract

The paper describes a digital control system of the rigid-flap wavemaker in a towing tank in CTO S.A. Ship Design and Research Centre. The control system is based on a 8-bit AVR microcontroller and consist of two cascading PID controllers. The digital system replaced the previous analog one from 1974 and has been integrated with the existing sensors and actuators of the wavemaker. The new control system allows to obtain a required repeatability of the generated waves.
