摘要/Abstract

摘要： 针对波浪复杂的变化特性和全封闭波浪发电系统，基于互联－阻尼配置的无源性控制(IDA-PBC)理论，提出了一种对波浪变化情况具有鲁棒性的控制算法．首先建立全封闭波浪发电系统的欧拉－拉格朗日模型(EL)，并根据系统结构和动力学特性进行模型分解，再基于李雅普诺夫稳定理论和阻尼注入的方法设计无源控制律，并推导出全封闭波浪发电系统最大平均输出功率下状态量期望值．在 Matlab/Simulink 仿真环境下搭建了全封闭波浪发电系统的仿真模型，进行了无源性控制的仿真分析．仿真结果表明，所设计的无源控制律能够实现给定状态量的快速跟随，且在波浪变化条件下，也能达到控制效果．

关键词: 波浪能发电, 互联－阻尼配置, 无源性控制

Abstract: For the complex characteristics of wave and the fully-enclosed wave power generation system，a control algorithm which is robust to wave changes was proposed based on interconnection and damping assignment passivity based control (IDA-PBC)． Firstly，a Euler-Lagrange (EL) model was established for fully-enclosed wave power generation system，and the model was decomposed based on the structure and dynamic characteristics of the sys- tem． Then，according to the Lyapunov stability and damping injection，a passivity-based control law was acquired． In addition，in order to maximize power generation，the desired control objectives were deduced． Lastly，a fully-en- closed wave power generation model in Matlab/Simulink simulation environment was built，and simulation analysis of passivity based control was carried out． The result shows that asymptotically tracking control objectives can be a- chieved，and the control law is also effective in case of wave changes．

Key words: wave power generation, interconnection and damping assignment, passivity-based control
