how to make this matlab simulink block diagram

RL=-√(Pg1/a2) + b2)(a1ΔPg + b1)

i'm working on simulation program right now and i don't know how to make this block diagram

[baihaki]

thanks for the answer. this really help me to understand the basic. however, do you know how to write Δ　in block diagram simulink

I believe in this case it would be the derivative with respect to time of Pg. Can't say for sure, but if it is you can use the derivative block to model it.

Modeling ODEs in Simulink should help you get started. This looks pretty straightforward.
