中文摘要:

波浪能是最复杂的一种可再生能源,这一特性导致其功率控制算法的实现性差。针对这一问题,文章基于一种全封闭的振荡浮子式波浪发电系统的动力学模型,构建波浪发电系统的端口受控的耗散哈密顿模型(PCHD),并设计无源性控制器,为改善系统动态响应在无源性控制器中注入阻尼。仿真结果表明,在波浪变化条件下,本系统能实现最佳状态的快速跟踪,且有良好的动态特性。通过采用PCHD模型,使控制器设计过程具有结构性的特点,物理意义清晰,设计简单。

英文摘要:

Wave energy is the most complex renewable energy, which leads to the poor implementation of its control algorithm. Aiming at this problem, this article is based on the dynamic model of a fully enclosed oscillating buoy wave energy converter, a port controlled Hamiltonian with dissipation(PCHD) is derived. Accordingly, the passivity controller can be designed. In order to improve the dynamic performance of the system, the damping is injected into the passivity based controller. Simulation results show that the converter system can rapidly track the best state and have an excellent dynamic performance when the state of wave changes. The system adopts a model of PCHD, which makes the designing process of controller have the characteristics of structural, clear physical meanings and the simple design.
