Testing and Analysis of Actuator Parameter Identification of Heavy Load Stewart Platform
Being relatively new to the field, electromechanical actuators of Stewart platform in vibration control and motion simulation applications lack the knowledge base compared to ones accumulated for the other actuator types, especially when it comes to characterization and system identification. This paper focuses in the modeling of an electromechanical linear actuator to be used in a heavy load six-degrees-of-freedom platform application intended for motion control technology. The paper keeps the main kinematic and dynamic parameters unaffected, ignoring others. After obtaining the structure of model, parameters is derived by system identification. Provides a comparison of output of real system and simplified model by same input signal, the experimental result shows that the method is accurate and have good ability.
