“…The lock actuator is linear actuator driven by a low-power permanent magnet synchronous motor, while latch and lift ones are rotary actuators driven by Alternating Current (AC) electrical motors. The part of ACE about the lock actuator refers to the literature [6]. Traditional AC motor control schemes use different types of relays, such as delay relays and overcurrent protection relays, through a large number of "wire-and" and/or "wire or" connections, which construct complex control logic [7].…”

An integrated airborne Actuator Control Electronics (ACE) based on Field Programmable Gate Arrays (FPGAs) has been designed to control the main cargo door motion of ARJ21-700 converted freighter. This paper illustrates the designing method of the ACE, and analyses the relationship between control timing and door slippage. In the experimental part, a prototype Main Cargo Door Actuation System (MCDAS) is constructed and tested. The results show that multiple actuators of the system move sequentially under the control of only one ACE, and the switching process is smooth. The cargo door can be parked at any position with small slippage, just by adjusting the reverse braking time parameters in the FPGA.
