This work presents a state feedback controller suitable to regulate the output voltage of DC-DC buck converters operating under input voltage disturbances and load variations. First. a state space model of the plant is given and the performance requirements are presented. in terms of bounds on rejection of disturbances. https://www.roneverhart.com/NeOn-Zero-Lefty-M390-BLADE-TITANIUM-HANDLE-MRBS-p11472/
