A Novel Way to Realize Standardization of UAV EMA Controller

Abstract UAV (Unmanned Aerial Vehicle) application is becoming wider and wider, its flight safety and performance is quite important. As one of its key components, EMA (Electronic Mechanical Actuator) plays a significant role in deciding UAV performance. In order to reduce cost, shorten design period and save human power, a novel way to realize standardization of the EMA controller is presented in this paper. Based on analysis of the typical EMA with DC (Direct Current) brush motor as its power source used in UAV, the standardization controller is designed. The generalized hardware platform is built with all the functional parts required. And then the communication protocol is made for EMA controller configuration. The upper computer software and the embedded software collaborates to conduct various controller functions. The standardization controller features modularization, combination and seriation, which is better than the traditional EMA controller for it saves cost and time. Several ground tests and flight tests prove its feasibility and validity.
