A fractional order sliding mode control (FROSMC) scheme based on parameters auto-tuning for the velocity control of permanent magnet synchronous motor (PMSM) is proposed in this paper. The control law of the proposed F(R)OSMC scheme is designed according to Lyapunov stability theorem. Based on the property of transferring energy with adjustable type in F(R)OSMC, this paper analyzes the chattering phenomenon in classic sliding mode control (SMC) is attenuated with F(R)OSMC system. A fuzzy logic inference scheme (FLIS) is utilized to obtain the gain of switching control. Simulations and experiments demonstrate that the proposed FROSMC not only achieve better control performance with smaller chatting than that with integer order sliding mode control, but also is robust to external load disturbance and parameter variations.
本文提出了一种基于参数自整定的分数阶滑模控制（FROSMC）方案，用于永磁同步电机（PMSM）的速度控制。所提出的 F(R)OSMC 方案的控制律是根据 Lyapunov 稳定性定理设计的。基于 F(R)OSMC 中具有可调类型的能量传递特性，本文分析了经典滑模控制（SMC）中的抖动现象在 F(R)OSMC 系统中得到了减弱。利用模糊逻辑推理方案（FLIS）获得开关控制的增益。仿真和实验结果表明，与整数阶滑模控制相比，所提出的 FROSMC 不仅具有更小的抖动和更好的控制性能，而且对外部负载干扰和参数变化具有鲁棒性。
