| Abstract: | 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. |
