研究了基于多个线性开关磁阻电机(LSRM)的闭环系统跟踪同步网络的可控性。LSRM网络是从全局闭环的方式构建的，闭环只回复来自领导节点的输入和输出信息。然后，将每个局部LSRM节点建模为一般二阶系统，利用基于最小二乘法的在线系统辨识方法推导出模型参数。其次，为了保证LSRM网络的可控性条件，推导了一个定理，阐明了LSRM网络的可控性、网络的图可控性和节点动态的可控性之间的关系。为了提高LSRM网络的跟踪性能，提出了一种状态观测器位于引导者的状态反馈控制策略。最后，仿真和实验结果验证了网络控制器设计方案的有效性，实验结果也验证了基于引导者的全局反馈策略不仅改善了LSRM网络的跟踪性能，而且提高了网络的同步精度。
This paper investigates the controllability of a closed-loop tracking synchronization network based on multiple linear-switched reluctance machines (LSRMs). The LSRM network is constructed from a global closed-loop manner, and the closed loop only replies to the input and output information from the leader node. Then, each local LSRM node is modeled as a general second-order system, and the model parameters are derived by the online system identification method based on the least square method. Next, to guarantee the LSRM network’s controllability condition, a theorem is deduced that clarifies the relationship among the LSRM network’s controllability, the graph controllability of the network and the controllability of the node dynamics. A state feedback control strategy with the state observer located on the leader is then proposed to improve the tracking performance of the LSRM network. Last, both the simulation and experiment results prove the effectiveness of the network controller design scheme and the results also verify that the leader-based global feedback strategy not only improves the tracking performance but also enhances the synchronization accuracy of the LSRM network experimentally.
