The present invention relates to an apparatus to control feedback linearization. According to the present invention, an apparatus to control feedback linearization in a pulse wavelength modulation (PWM) DC distribution system including DC and AC power comprises: a command value generation unit to generate a command value from an input voltage and an inverter output current which passes a low pass filter (LFP); a follow control unit calculating an error value between the command value and power value fed back from an active DC filter, and receiving a calculation value to calculate a control value for removing a normal state error; a decoupling unit receiving and linearizing the control value to generate a PWM voltage command value; and the active DC filter controlling an inverter dependent on the PWM voltage command value, measuring a transformer input voltage and an inverter output current through an LC filter, calculating a measured value to output a power value, and feeding back the power value to the follow control unit. According to the present invention, since a PWM DC distribution system linearizes a non-linear system through feedback linearization control to reduce voltage fluctuation of a serial bus, a bandwidth of a voltage controller is increased and thereby dynamic characteristics are improved. |
