# OSFRA
 An Open-Source System Frequency Response Analyzer
## DSP_LIB
 DSP LIB is used to estimate the parameters of the system.
 
 The system, as shown in the figure, can be divided into analog domain and digital domain.

 It is very easy to get:
 
 (1)GH = e^(theta_feedback) / e^(theta_error) = e^(theta_feedback) / (e^(theta_reference) - e^(theta_feedback))
 
 (2)H = e^(theta_control) / e^(theta_feedback)
 
 (3)CL = e^(theta_reference) / e^(theta_feedback)
 
 **As e^(theta_reference).I is almost zero, some simplifications can be made.**
 
 This is the main algorithm in DSP LIB, besides there are some supporting codes.
 ## HOST_APP
 HOST APP is used to displaying the frequency response and compute the best control parameters.
 
 Recently, it is not finished yet.
