I am working on standalone system facing difficulty in setting up parameter of PI controller of inner current and voltage control loop. Can any one suggest some ways how can i tune PI parameter for proper switching and control of AC grid?
Mitul Shah If you use Matlab software, in 2014 and above, you can find the parameters Kp and Ki (zegler coefficients) in a direct way without calculation, (in the PI Controller Block, you adjust the depreciation, the steady state, and the response time, in the end you get the coefficients directly
