职称论文发表

摘要: 职称论文发表期刊研究了具有执行器饱和的网络化控制系统的镇定和~$L_2$ 增益控制问题. 基于切换系统模型, 得到了网络化控制系统的镇定条件, 且为了估计到一个更大的吸引域, 提出了相应的最优化问题. 在零初始条件下, 设计了状态反馈控制器, 能够保证系统从扰动 到控制输出的~ $L_2$ 增益小于等于一个给定的常数. 作为进一步的讨论, 通过利用一个松弛的界定条件, 提出了改进的镇定条件. 最后, 数值例子和仿真验证了所得结果的有效性和价值.

Abstract: This paper investigates the stabilization and $L_2$ gain control problems of networked control systems with actuator saturation. Based on the switched system model, stabilization condition of networked control systems is obtained, and the corresponding optimization problem is presented to estimate a larger attractive region. Under zero initial condition, state feedback controller is designed which can guarantee the $L_2$ gain of systems from the disturbances to controlled output less than a given scalar. As the further discussion, the improved stabilization condition is proposed by using a slack bound condition. Finally, numerical example and simulations illustrate the effectiveness and values of the obtained results.
Keywords: Stabilization; $L_2$ gain control; Networked control systems; Actuator saturation
