Tool/software: Code Composer Studio
Firstly,I have test the bode plot of my power stage which is a buck circuit by the SFRA software.The results is behind the picture.
Secondly,I want to gain the parameter of the Compensator in the Software -CompDesigner by the data obtained through the SFRA.But I found many problems.
Problems:
1、If i load the different data from the red framecase (Browse SFRA csv dat), I will find the same coefficient in the Comp Coeff when i choose the same Compensator model ,such as ,2p2z、3p3z.
2、if i load the Comp Coeff to the code in CCS6.2,I found the results are worse because of the output voltage isn't stable and leading to the inductance squealling in the close loop.
thirdly ,I also find the examples in the D:\controlSUITE\development_kits\BOOSTXL_BUCKCONV\v1_00_00_00\Buck_VMC_F28069M gives the five kinds of Comp Coeff.Therefore,I want to gain the next help.
1、How to gain the perfect Comp Coeff so that assures the stable output voltage,and give me a emphasis about the above questions.
2、Could you help me provide the detailed datasheet about Software -CompDesigner.you can also give me another advice.
Thank you very much.
