Abstract: A method includes applying a high frequency signal to an electromechanical actuator and measuring a first response of the electromechanical actuator to the high frequency signal, estimating electrical parameters of the electromechanical actuator based on the first response, applying a low frequency broadband signal to the electromechanical actuator and measuring a second response of the electromechanical actuator to the low frequency broadband signal, and estimating mechanical parameters of the electromechanical actuator based on the second response and the estimated electrical parameters.
