A Multi-objective Control Algorithm for Micro Grid with Flywheel Energy Storage Supporting System

提出一种基于Youla参数和依赖独立李雅普诺夫函数为每个目标的多目标控制算法,并将其用于微电网用飞轮储能支承系统中。在假设悬浮转子系统性能的柔性与刚性相互独立的基础上,建立了柔性转子的结点状态空间模型和刚度模型,并结合了闭环控制回路中的其它环节,建立了微电网用飞轮储能的磁悬浮支承控制系统模型。在详细介绍了形成线形矩阵不等式的矩阵控制和一般的算法的基础上,对所设计的控制器作了分析和与传统控制器作了比较,实验结果表明所提出的多目标控制算法精确有效。

We present here a multi-objective control algorithm based on the use of Youla parameterization and an independent Lyapunov function for each objective and it used for the micro grid with flywheel energy storage supporting system. The model we use has been developed as follows: we consider that the rigid and flexible behaviour of the system are independent. Thus, we develop a nodal state space model of the flexible shaft, the rigid equations of the system and combine with other links in the closed loop to build a complete model of the AMB suspended system. We introduce the matrix manipulations that lead to the final LMIs and the general algorithm as detailed. The controller we obtain is analysed and compared to the initial one. The experimental results show that the proposed multi-object control algorithm is accurate and effective.
