| 中文摘要 |
| 本文给出两种观测器，一种是基于龙勃格观测器和自适应理论的转子磁通观测器，当转速未知时该观测器仍然具有较高的观测精度；另一种是转子转速的非线性观测器，在该观测器中，转子转速是状态变量而非参数，克服了线性观测器中将转子转速作为参数带来的电机瞬间过程中转速观测不准的缺点，并在此基础上给出负载转矩的估计公式，给出了仿真结果。 |
| 英文摘要 |
| This paper presents two kinds of estimator.The first one is a rotor flux observer based on the Luenberger observer and adaptive theory. The advantage of it is the highly observing precise in spite of the unknown rotor speed. The other one is a nonlinear observer for observing rotor speed which can observe the rotor speed precisely not only in statistic state but also in dynamic is displayed in the last. |
