“…Ali, T. et al used PI control to complete the speed and position control of the aircraft cabin door, such that the accurate door model system integrated with BLDC improved the torque [16]. Alzuabidi, Ohaa et al conducted an analytical modeling of the PWM speed control of a permanent magnet brushless DC motor (PMBLDC), which consists of a voltage source inverter, a Hall sensor, a PI controller, and a circulation circuit [17]. In particular, a second-order low-pass filter is added to the PI controller in order to reduce the harmonic content of the inverter current.…”

Typically, the current and speed loop closure of servo motor of the parallel platform is accomplished with incremental PI regulation. The control method has strong robustness, but the parameter tuning process is cumbersome, and it is difficult to achieve the optimal control state. In order to further optimize the performance, this paper proposes a double-loop control structure based on fuzzy integral and neuron proportional integral (FI-NPI). The structure makes full use of the control advantages of the fuzzy controller and integrator to improve the performance of speed closed-loop control. And through the feedforward branch, the speed error is used as the teacher signal for neuron supervised learning, which improves the effect of current closed-loop control. Through comparative simulation experiments, this paper verifies that the FI-NPI controller has a faster dynamic response speed than the traditional PI controller. Finally, in this paper, the FI-NPI controller is implemented in C language in the servo-driven lower computer, and the speed closed-loop test of the BLDC motor is carried out. The experimental results show that the FI-NPI double-loop controller is better than the traditional double-PI controller in performance indicators such as convergence rate and RMSE, which confirms that the FI-NPI double-loop controller is more suitable for BLDC servo control.
