    摘 要:针对传统控制器在永磁同步电机调速系统中转速超调大、抗扰动能力不足等问题,在指数趋近律的基础上添加了时变函数,提出了一种自适应能力更好的分式指数趋近律滑模控制 (SMC) 系统,并在 MATLAB/Simulink 上进行仿真,将该控制系统与传统的 PI 控制系统和指数趋近律滑模控制系统进行对比分析,结果表明,分式指数趋近律在速度环控制上几乎未发现超调问题,并且减少了电机的转矩波动,提高了电机调速系统的抗干扰能力,在保持系统稳定,减少电机能源损耗,提升能源利用率方面有较大成效。

    Abstract: The traditional controller has many problems. For instance, the speed overshoot is over the given range. Another problem could be the anti-disturbance capability is not enough. This research added the real variable function based on the exponential approach law. It proposed a fractional exponential reaching law SMC system with better adaptive ability. In addition, simulation experiments have been conducted in MATLAB/Simulink. This paper compared the proposed control system, the traditional PI control system, and the exponential reaching law SMC system. The result shows that the controller with the fractional exponential approach law has better control ability of the speed loop. Moreover,it reduces the torque ripple of the electric motor and promotes the immunity of the speed governing system. The new design could help keep the stability, reduce the energy consumption of the electric motor, and increase energy efficiency.
    Key words: exponential reaching law; permanent magnet synchronous motor; sliding mode control system; energy consumption
