Previous Research On The System For Prototype Large Flume Wave Generating

In the hydraulic experiments, the accuracy and reliability of results depends on the model and the experimental environment. So it needs to be solved the problems between the wave and structure interaction,and it must improve and enhance the laboratory wave simulation techniques constantly. That is,it must generate the waves,which can match the actual wave of the engineering environment in mechanical properties and statistical characteristics.By establishing the prototype large flume,it can capture the scene of the physical phenomena,which is difficult to get in the outdoor. And it can reveal the inherent law of the motion,which provides the basic for utilization of offshore deep-water port, harbor deep water research, water transport environmental protection and safety.Based on the Tianjin Water Transport Engineering Institute of Water application infrastructure technology,this paper uses the theory of the prototype research home and abroad,which does some previous research on the prototype large flume of the wave generating system by using the motor servo control system.This paper describes the basic condition on the prototype large flume.It establishes the formula model of the servo motor,and it combines the technology of SVPWM.By using the MATLAB to stimulate the established model,it can be seen that the model is accurate and feasible.This article describes the principle and characteristics of the internal model control.And it establishes and analyses the control system based on the internal model control.It uses the MATLAB to stimulate the control system.It is shown that the established model of prototype large flume of the wave generating system has good dynamic response and stability.
