Research on control law of more-electric aircraft environmental control electrical system based on fuzzy control

The environment control system of more-electric aircraft adopts the permanent magnet speed motors to drive the air compressor, which improves the efficiency of air engine and reduces the fuel consumption, but has a higher requirement for the temperature control accuracy in the meantime. At present, the temperate control law build upon PID control principle is adopted in current aircraft environment control system, however, PID control has certain detects in parameter setting and anti-disturbance performance. In this paper, the application of Fuzzy Control law for environment control electrical system of more-electric aircraft is studied, and the system is simulated and verified by Matlab. At the same time, the control effects of PID, Incremental PID, Fuzzy Control are compared and analyzed, and the advantages of Fuzzy Control in dynamic characteristics and adaptive ability are verified.
