Abstract: In this paper,introduced a kind of aviation actuation system made up of brushless DC motor(BLDCM)and mechanism of worm and gear.For the requirement of performance,the strategy of three closed loops control including position loop,speed loop and current loop were adopted.The control system was modelled and simulated in Matlab/Simulink.And the simulation results show that the time of response characteristic is shorter and precision is higher in the whole control system.The method of three closed loop control is feasible in aviation actuation system based on BLDCM.
