Actuator is widely used in the control system. Among all characteristics of an actuator, dynamic stiffness is an important indicator; it must satisfy the requirement to inhibit the control surface’s flutter. This article described the definition of dynamic stiffness of actuator, introduced the importance of the research of dynamic stiffness of actuator, designed a test bench for dynamic stiffness testing and putted forward a method which based on Programmable Logic Controller to simulate a signal generator which generated sinusoidal signal load to test the dynamic stiffness of actuator, found out a worst point of the actuator’s dynamic stiffness, improved the stability of the actuator system and avoided the occurrence of flutter at the frequency.
