摘要
介绍了一种为某型无人驾驶直升机研制的新型电动舵机系统。该系统采用了航空精密微型滚珠螺旋副和基于智能功率集成电路（ＳｍａｒｔＰｏｗｅｒＩＣ－ＳＰＩＣ）的ＰＷＭ（ＰｕｌｓｅＷｉｄｔｈＭｏｄｕｌａ－ｔｉｏｎ）伺服放大器，具有精度高、频带宽、线性度好、效率高和线位移输出方式等特点。文中详细描述了该系统的设计思想和结构特点。频响测试和机载试飞表明：这种新型的电动舵机系统具有良好的动态响应过程。
A new electromechanical actuation system designed for unmanned helicopter is introduced. A micro ball screw and PWM(Pulse Width Modulation) servo amplifier based on Smart Power IC SPIC are applied in this system. Higher accuracy, band width, linearity, efficiency and linear displacement output are characteristics of the system. The design consi derations and structure features of the system are discussed carefully and thoroughly. The result of test and experiments on line proves that the design of this system is successful and the system exhibits satisfied dynamic response.
