摘要
本文在交流电机双轴理论的基础上,以异步电动机转子磁通和定子电流为状态的状态方程为模型,推导出一种新的异步电机磁通观测器。再用一种新的开关电容网络来模拟状态方程和观测器,得出一种实用的开关电容模拟电路,本观测器的开关电容电路简单,收敛速度快,仿真和实验结果表明它具有乐观的应用前景。
Based on the two- axis theory of the induction motor, a mould of state equation by using the state of rotor flux and stator current to derive a new kind of asynchronous motor flux observer, And then using new kind of switched capacitor networks (SCN) to simulate state equation and induction motor flux observer,a kind of practical SCN is obtained. Its structure is simple, convergence speed is fast.Simulation and experiments show that the new SCN has high application prospect.
