Abstract: 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.
