摘要研究二维分布参数系统在传感器执行器网络下的控制问题.传感器执行器网络由二维平面上固定的传感器与移动的执行器组成.首先,利用传感器对二维分布参数系统的测量信息设计观测器,用来估计二维分布参数系统的状态,并在观测器的基础上给出相应的控制器;然后,利用算子半群理论并结合Lyapunov方法,得到平面上移动的执行器的水平运动速度和垂直运动速度,该速度依赖于观测器的信息;最后,数值仿真表明,二维分布参数系统在该移动执行器控制下的性能得到了有效的提高. The control problem of two-dimensional distributed parameter systems in sensor and actuator networks is investigated.The sensor and actuator network consists of fixed sensors and mobile actuators on the two-dimensional plane.Firstly,an observer is designed using of the measurement information provided by the sensors to estimate the state of the two-dimensional distributed parameter systems,and the controllers are given based on the observer.Then,by using the operator semigroup theory and Lyapunov method,the horizontal velocity and the vertical velocity of each actuator are given based on the observer.Finally,a numerical example is given to illustratie that the control performance of the two-dimensional distributed parameter systems can be improved by the mobile actuators.
