| 摘 要： | 针对在异步电动机调速系统中,负载转矩通常是变化和不易测量的特点,设计了负载转矩观测器来观测负载转矩,并利用负载转矩观测值对非线性状态反馈解耦控制律进行在线调整,从而保证了异步电动机控制系统的非线性解耦.最后利用计算机仿真工具MATLAB对负载转矩观测器进行了仿真分析,结果证实是有效的.

| Abstract: | Aiming at such characteristics that the load torque in asynchronous motor system is usually variable and is not easy to measure,a load torque observer was designed to observe the load torque.The observation results were used to modify online the nonlinear state-feedback control law to ensure the nonlinear decoupling of the asynchronous motor control system. Finally,the MATLAB was used to simulate the load torque observer,and the observer is proved to be valid by the simulation result. |
