| 摘 要： | 针对网络控制系统中存在不确定时延的问题，讨论了网络条件下感应电机的建模与控制．首先基于感应电机的非线性数学模型，运用直接反馈化方法将其线性化，然后在线性化的基础上引入具有时延的网络控制系统，建立了感应电机的网络化控制模型．运用李亚普诺夫函数方法，给出了闭环系统渐近稳定的充分条件，基于相应的线性矩阵不等式可行解，可以求解状态反馈控制律．最后，仿真结果验证了该方法的有效性．

| Abstract: | Considering the uncertain delay of networked control systems,the networked modeling and control of induction motor is studied.Firstly,based on the nonlinear mathematical model of the induction motor,the direct feedback linearization method is used to linearize the nonlinear system,and then th e networked control system with time-delay is introduced into the system,whereby a networked control model of induction motor is established.By using Lyapunov functional approach, the sufficient condition of asymptotic... |
