hello everyone,
I am new to here and i am really struggling with my non inverting buck boost converter design. the first one is control, as i am going to use PID control for voltage and inductor current. as i have no transfer function of my circuit, i am going to use SLPS from matlab to tune the PI control value, i tried to tune it manually for three days and it is no where near to get the values. is there anyone can give me an advice for that please.
second problem is that i am going to MBED1768 micro-controller for control and i am struggling for writing code in relating with inductor current control. i am not sure on how to relate with output voltage control and inductor current control. Do they need separate loop for control.? thanks for helping me guys, my switching frequency is 100khz. i attached my circuit topology.
