中文摘要	异步电机间接矢量控制在电力传动领域应用广泛。该控制方案依赖于电机的互感和转子电阻等参数。这些参数往往在运行中发生变化,从而导致驱动系统控制性能下降,在以转矩为控制目标的电动汽车驱动系统中该问题尤为突出。本文推导了间接矢量控制中电磁转矩和转子磁链与电机参数偏差之间的关系式。通过引入稳态转子磁链观测器,提出利用稳态转子磁链的幅值和位置角偏差对互感和转子时间常数等的倒数进行在线校正的新算法。该稳态转子磁链观测器以电压模型为基础,但其中的积分环节可转化为简单的代数运算,避免了纯积分数值计算所需的特殊处理。仿真和实验验证了新的校正算法在改善转矩的控制性能方面的有效性。; Indirect field oriented control of induction machine is widely used in a lot of industrial applications. The performance of the control scheme, however, strongly relies on the parameters of the motor, e.g. the rotor resistance and mutual inductance between rotor and stator of the motor. The variance of the parameters in operation results in decline of the control, that is vital especially for the torque control in electric vehicles. In this paper, the effects of parameter errors including rotor resistance and mutual inductance, on the rotor flux and the electromagnetic torque are discussed in details. A new scheme of tuning parameters on-line via the steady state voltage model based rotor flux estimation is proposed, in which the inverses of rotor time constant and mutual inductance are corrected by the error of phase angle and magnitude of the rotor flux. The simulation and experiment results validate the effectiveness in improving torque control of the new method.
