Power-stage frequency response cancellation of DC-DC converter with digital control

Selecting appropriate fuzzy PID control structure for power electronic applications

“…The circuit parameters of the buck converter are as follows [6]: L = 220 μH, C = 330 μF, R o = 5 Ω, R L = 68 mΩ, R C = 25 mΩ, V in = 10 V, the switching frequency is f sw = 20 kHz, and the sensor gain is H s = 0.5, and the sampling time T s = 50 μs ( f s = f sw ). A well‐known pole‐zero cancellation method presented in [17, 18] is utilised to determine the PID gains ( i.e. q 0 , q 1 , and q 2 ).…”
