The analog data acquisition system developed in this paper is integrated into the remote interface unit of aircraft. It uses the high certainty and high real-time performance of the IEEE-1394B bus to realize information interaction with the aircraft backbone network, and participates in sensor closed-loop regulation and state information feedback. Using DSP + FPGA architecture, the functions of bus communication, high-speed data acquisition and decoupling control are realized. The normalization design of analog data acquisition is realized by using table driving and dynamic switching technology. The method of error calibration is applied to realize high-precision acquisition. The system software is divided into acquisition layer, interpretation layer and application layer, which has strong portability. The experimental results show that the acquisition accuracy is high, which can meet the requirements of aircraft analog data acquisition. The system developed has the characteristics of high real-time, generalization, miniaturization and strong data processing ability.

The electronic-mechanical actuator servo control system designed in this paper is integrated in the aircraft remote execution unit. It uses the IEEE-1394B bus to realize the information interaction with the aircraft backbone network, and uses the basic topological with ring to realize the fault tolerance of a disconnection. Through pre-distribution broadband technology, the deterministic transmission of control commands is realized. The system adopts DSP+FPGA architecture to realize the decoupling control between bus communication, algorithm control, motor protection and BIT logic operation. The DRV8301 driver is used to realize power conversion and three-phase power bridge drive with overcurrent, undervoltage, overvoltage, overheating and other protection functions. By configuring the Hall sensor and quadrature encoder at the same time, it can realize the margin acquisition of the rotor position. The experimental results show that the system designed in this paper is simple, reliable, and time-deterministic, it can be widely used in the flow, pressure and temperature adjustment of the network nodes in each area of the aircraft.

This paper presents a comparative simulation and experimental studies, related to proportional plus integral (PI) and fuzzy PI speed control in Brushless DC Motor (BLDCM) based on the dSPACE real-time system. The control strategies have been designed in MATLAB/Simulink and implemented on the dSPACE platform. The on-line parameters have been debugged by ControlDesk. The speed responses, obtained under PI and fuzzy PI speed control, both in low and high speed, are recorded and compared for a variety of operating conditions. Finally, the simulation and experiment results verified the feasibility and the validity of control schemes.
