摘要
基于分数阶文积分和自抗扰控制,设计了永磁同步电机转速伺服控制系统。该方法采用分数阶微积分比整数阶更广的参数稳定域的特点,与自抗扰控制对未知干扰的高观测性能结合,同时,采用双线性变换和连分式展开法推导出分数阶积分的离散模型,建立分数阶比例积分非线性反馈环节,以增强系统对扰动的鲁棒性能。仿真试验中,将其与采用非线性函数的自抗扰控制器进行了比较,结果验证了所提出的方法的有效性。
Based on fractional order calculus and active disturbance rejection control （ADRC）, a robust control system with permanent magnet synchronous motor （PMSM） speed servo was presented. Fractional order calculus spread the stable region of the system parameters, the ESO has good performances of observing the unknown disturbances. By bilinear transformation and continued fraction expansion, the discrete model of fractional order integral was obtained. Then, the fractional order proportional integral nonlinear feedback was established to enhance the robustness of system against the disturbances. Compared with ADRC using nonlinear function, simulation results verified the effectiveness of the proposed control method.
