摘要:

Abstract:
 In order to improve the current tracking performance of unified power quality conditioner,a
double hysteresis current control method based on the optimal voltage space vector was proposed. Firstly
the optimal voltage vector output was selected to control the phase error current quickly according to the
location area of error current vector and the error current beyond the mark or by not using the ordinary
double hysteresis control method. Although this method ensures a fast current response,decreases highorder
harmonics and limits the switching frequency,it decreases the compensation accuracy because the
inverter is kept in the former state when the error current is in the inner loop. In view of this problem,
the active disturbance rejection controller was used in the control of inner loop. The load current and the
source voltage were contributed to total disturbances and the expending state observer was used to estimate.
Then the disturbance was compensated by the nonlinear state error feedback control law. So the
complicated current reference calculation was avoided,which make the system adaptive to the different
load. At last,the PSO algorithm was used to optimize the parameter in the ADRC controller. Compared
with other current control method, this method improves the utilization ratio of voltage. The software simulation
on MATLAB and the hardware experiment on DSP are presented to verify good static and dynamic
performance,and strong robustness of the proposed control strategy.
