The modeling and simulation analysis of micro digital servo actuator

The micro digital servo actuator is useful in same specific control system, many of the simulation researches of servo actuator are huge and used in large equipment as missiles, aircrafts and robots, so the simulation of micro digital servo actuator become very import in evaluate system control performance. So this article through the structure analysis of the micro actuator, combined with the parameters of the actuator and internal motor given by manufacturers, the mathematical models of each part in the actuator are established respectively. Then the simulation of the motor and the actuator mathematical models are designed by Matlab/Simulink. The simulation results show that the motion characteristics of the micro servo actuator under different loads are consistent with the physical micro servo actuator and the simulation model has high authenticity and reliability.
