The control device includes a FB controller which generates a first time value for switch-off timing as the amount of feedback control, a machine learning controller which generates a second time value for switch-off timing as the amount of FF control, and a difference time calculator which obtains a difference between the first time value and the second time value and transmits a difference signal to the drive circuit. The machine learning controller calculates a second time value by multiplying the deviation between the target value of the machine learning control and the estimation value from leaning history in certain sampling by α=A·e×p(−λ×n) (A: a factor (except for zero) for suppressing the first undershoot, λ: a factor (constant except for zero) for suppressing the second undershoot, and n: an integer indicating the nth sampling)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control device for DC/DC converter","description":"Disclosed herein is a control device for a DC/DC converter, in which FB control and FF control are combined to estimate an output voltage of a nonlinear dynamic system while guaranteeing stability.
