Difficulty in getting inverter transfer function

5 次查看(过去 30 天)
Hi, i want to design an inverter with controllable output AC voltage. To check PID controller action i require full bridge inverter transfer function as that is my plant in model. full bridge inverter has DC value and 4 gate signals as input. It has AC wave as output. i am not getting this tranfer function to verify PID action. as i have seen examples given by mathworks, it seems that it requires transfer function to verify PID control action.please suggest a way.

It would be helpful if you attach your model and MATLAB code, and explain what you tried already and what exactly does not work

Transfer function of a inverter is pretty complex . PID control can be achieved without knowing the system transfer function also. Try Ziegler-Nicholas method of PID tuning.

Hello ashish,
I also want to derive transfer function of full bridge inverter , can you share details if you have transfer function for full bridge inverter ?
