摘要: In this paper, a fractional-order active disturbance rejection controller (FOADRC), combining proportional derivative (FOPD) and an extended state observer (ESO), is proposed for permanent magnet synchronous motor (PMSM) speed servo system. The global stable region in the parameter (Kp, Kd, μ)-space corresponding to bandwidth ωo can be obtained by D-decomposition method. To achieve satisfied tracking anti-load performance, optimal ADRC tuning strategy proposed. This applicable both FOADRC integer-order (IOADRC). method not only meets user-specified frequency-domain indicators but also achieves time-domain performance index. Simulation experimental results demonstrate that better tracking, more robustness external performances than traditional IOADRC typical Proportional-Integral- Derivative (PID) controller. For example, JITAE of designed are less 52.59% 55.36% PID controller, respectively. Besides, 17.11% 52.50%
