摘要
在矢量控制异步电动机数学模型的基础上,针对电机转子电阻和贞载转矩变化的不确定性,应用非线性控制的理论,设计了一个渐近跟踪负载转矩和转子电阻实际值的非线性辨识算法,实现了参数的自动跟踪,并建立了非线性自适应控制的方案。仿真结果表明,辨识算法具有快捷准确的优点,使系统具有一定的鲁棒性和较好的稳、动态性能。
An adaptive control project and parameter identification method for vector-controlled induction motor is presented in this paper. The rotor resistance and load torque are identified based on nonlinear control theory to follow the practical values. The identification method has the advantages of rapid and correct convergence. The simulation results demonstrate that the method and project are effective. The system shows a good performance.
