Wave channel systems provide crucial experimental platforms for the development and optimization of wave energy converters. By enabling the safe and repeatable simulation of real ocean conditions, these systems play a key role in understanding wave behavior and reducing design risks. They allow the generation of a specific wave model to investigate the effects of water waves on coastal structures, coastal ecosystems, and offshore platforms. In this study, a hydraulically controlled piston-type wave generator was utilized in a 24-meter-long wave channel, which measures 1 meter in width and 1 meter in height, to produce regular waves. The wave generation system in the channel is operated by a hydraulic cylinder with a 400 mm stroke, controlled by a proportional directional control valve. An NI-CRIO 9074 programmable automation controller (PAC), featuring Field Programmable Gate Array (FPGA) technology and an NI-9263 analog output module with 15-bit resolution, was used for controlling the proportional directional control valve. The cylinder position was measured at 15-bit resolution using an NI-9215 analog input module. A proportional-integral control (PI) technique was implemented on the NI-CRIO 9074 hardware. The controller gains were determined experimentally, with a computer employed to perform real-time measurement and data logging of the generated waves. The entire system is managed by the NI-CRIO 9074 and regular wave production is achieved through LabVIEW-based user interface programs running on the computer.
