摘要
为了适应多电/全电飞机的发展,提出了一种带有离合器的机电作动器(EMA)。针对该EMA的丝杠螺母副驱动方式,设计了一套数字伺服控制系统。通过对EMA电机和传动部分模型的建立,完成了控制器的软硬件设计。同时,分析了各参数对EMA伺服控制系统的影响,并进行了仿真验证。仿真结果表明,基于EMA实际模型的复杂性设计的模糊PID自整定控制策略,取得到了较好的控制效果。
In order to accommodate multiple -electric /all-electric aircraft application , it proposes a kind of E-lectromechanical Actuator ( EMA ) with clutch , designs the digital servo control system for the drive mode of screw nut in the EMA .Through the establishment of motor model and transmission model in the EMA , it com-pletes the hardware and software of the controller .Meanwhile ,it analyzes the effects of each parameter to EMA servo control system and takes the simulation for validation .Based on the complexity of the actual model of EMA, it proposes the fuzzy self-tuning PID control strategy , and shows a good control effect .
