摘要： By adding a suppression amount for suppressing an overshoot or undershoot that attenuates with time during an overshoot or undershoot period, the overshoot or undershoot can be suppressed within a short time and the output can be made close to a normal value. When an output has overshot, an overshoot suppression amount including a time-dependent attenuation suppression amount is added to an output feedback control amount, the time-dependent attenuation suppression amount being defined in a period during which the output overshoots. Alternatively, when the output has undershot, an undershoot suppression amount including a time-dependent attenuation suppression amount is added to the output feedback control amount, the time-dependent attenuation suppression amount being defined in a period during which the output undershoots.

A digital signal generating circuit converts the analog signal to the digital signal.

摘要： 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. 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).
