A motion control method and system for a wave generator

Abstract

The invention relates to the field of wave simulation, in particular to a wave maker movement control method and system. According to the control method, made forward wave shapes and target wave shapes are compared, so that the forward wave shapes are regulated; finally, forward waves or inclined waves meeting user requirements are obtained. The wave making mode is simple; the wave making speed is high; the control precision is high; a corresponding control system uses a host computer and a controller for controlling a wave making unit; the cost performance is high; distribution wires are saved; the control structure is optimized; the energy consumption is reduced; the communication is faster and more stable; the control precision is higher; the requirements of synchronism and real-time performance of a wave making control system are met.

Description

technical field [0001] The invention relates to the field of wave simulation, in particular to a motion control method and system for a wave maker. Background technique [0002] It has become an important means of ocean engineering experiments to reproduce the random motion of ocean waves through the wave maker system, and the wave maker has also become the basic equipment of ocean engineering laboratories around the world. The wave maker mainly uses controllable equipment to simulate the real sea state as much as possible, and provides a reliable sea state physical model for various marine scientific experiments, thereby helping marine engineering researchers to analyze different marine structures, such as docks, ports, ships, Seaplane and other designs provide basis to ensure the economy, safety and reliability of project engineering. According to the wave-making method, the wave-making machine is mainly divided into two types: mechanical type and air-compressed type, and...

Problems solved by technology

The wave maker control system driven by an AC servo motor in the prior art is composed of a host computer, a motion controller, a servo driver, and an AC synchronous permanent magnet servo motor. The host computer is usually a PLC, a numerical control system or a single-chip microcomputer system with a motion control function , but since the number of wave-making plates that need to be controlled reaches 120-360 or even more, it is necessary to perform synchronous real-time control on 120-360 servo motors. This control method in the prior art is not only difficult to meet the requirements of the wave-making system. synchronization and real-time requirements, and there is also an error between the wave height of the generated waveform and the wave height of the target waveform, which will affect the results of subsequent experiments
