Research on Robust Control of Induction Machines Based on Auto Disturbance Rejection Controller

提出采用自抗扰控制技术设计异步电机矢量控制系统,以克服负载扰动、被控电机参数变化、以及建模误差等"内扰"、"外扰"对系统控制性能的不利影响。在MATLAB环境下对提出的异步电机鲁棒矢量控制系统进行了仿真对比研究,结果表明其各方面性能均优于基于PI调节器的矢量控制系统;在TMS320F2812 DSP开发环境中编写程序,进行了实验对比研究,结果表明提出的ADRC矢量控制系统的鲁棒性明显优于PI系统,方案可行、有效。

A new active disturbance rejection controller （ADRC） based field-oriented control （FOC） system of induction machines is proposed in order to overcome the side-effects of internal disturbance and external disturbance, such as the load disturbances, the motor＇s parameter disturbances and the model- ing error etc. Simulations compared with the PI adjustor based FOC system are performed. The results show that the performances of the proposed scheme are better than the PI system. Finally, the program is written under the development environment of TMS320F2812 DSP. The experimental results show that the performances of the proposed robust control system based on the ADRC are better than the PI system and the scheme is feasible and effective.
