摘要
文章介绍了一种由无刷直流电动机和蜗轮蜗杆机构组成的航空作动器系统。为了满足系统的性能指标,采用了位置、速度和电流三闭环的控制策略。在Matlab/Simulink环境下建立系统模型并进行仿真,结果表明该控制系统具有较快的响应特性和较高的精度,应用于航空作动器是可行的。
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.
