| 摘 要： | 稳定性问题的研究在感应电动机直接转矩控制(DTC)中具有重要意义。现有文献主要关注恒转速情形,本文研究更接近实际的情况一一变转速下的DTC稳定性,引入状态反馈机制,首先给出定子磁链控制律存在的充分条件;然后在参考转矩大于或小于负载转矩的情形下,分别给出了转矩控制律存在的充分条件,最后以数值仿真验证了所提控制律的有效性,磁链和转矩相对于参考信号的波动确实是限定在一定容差范围内。 |
| 关 键 词： | 感应电动机 控制 磁链 转矩 稳定性 |

| Abstract: | Stability plays an important role in the direct torque control (DTC) of induction motors.The issue in the condition of constant rotor speed was extensively studied in previous works.The problem of variable rotor speed,which is often the real case in the applications,is studied in this paper.Based on the state feedback controllers scheme,the sufficient conditions for flux amplitude regulation is presented and proved at first.For the torque reference being larger or less than the load torque,the sufficient conditions for torque regulation and their mathematical proofs are also given respectively. Finally,the simulation results show the effectiveness of presented methods. |
| Keywords: | induction motors control flux torque stability |
