Abstract

As the important executive body of flight control system, the servo aims to drive the control surface deflection according to the position command. This paper makes a hardware design for a digital electric-mechanical servo controller for valve adjustment. Three-phase brushless DC motor(BLDCM) acts as the core executive body. The system selects DSP + CPLD as the main control unit and the high-precision Linear Variable Differential Transformer (LVDT) as the position sensor. We achieve the digital control through the realization of three closed-loop control strategy including current loop, speed loop and position loop. Experimental results show that the system has high dynamic response speed and great precision static performance.
