Abstract

Linear electro-mechanical actuator is used as a core component of large space mechanic and its position is measured by resolver. Velocity of the linear electro-mechanical actuator is calculated by the position data using the simple difference which always caused the phase lag issues. In order to reduce the phase lag, luenberger observer has been designed and analyzed. According to the specific parameters of the servo system and closed loop control structure, luenberger observer for compensation is designed in velocity loop. Simulation model is established by Simulink which showed that the luenberger observer can effectively reduce the phase lag caused by the simple difference of resolver data and improve servo system's dynamic response significantly.
