kindly do this on simulink and attach the screen shots of simulink model and results. plz don't copy from chegg.

Add disturbance and feedforward in the Simulation of Buck converter in Matlab Compare the performance of (a) feedforward+feedback; (b) feedback and (c) open loop in the presence of disturbances in source voltage and reference: you may also consider having a variable load. Submit the screenshots of simulink simulation along with a comparison of plots of inductor current and capacitor voltage in open/closed loop. Vg step: initially 20 , then 40V Reference step initially 5 , then 10 Saturation after PID: lower limit 0.01 , upper limit 0.99 1. In this part you have to run the simulations of buck converter Buck Converter This example shows the operation of a buck converter
