Abstract: This paper introduced a kind of electromechanical actuator test system based on dSPACE. The test system architecture, mathematical modeling, data collection , and user graphic interface were introduced in details.  Using simulink tool in Matlab and ControlDesk in dSPACE, the test system was built. Using a small electromechanical actuator as the test object, the system was verified. The test results show that the system is stable and reliable and can meet the test requirements of the electromechanical actuator based on digital and analog signals.
