“…In [19], the DOV controller is used to correct the power factor and to reduce line harmonics. In [20], a direct output voltage control strategy is proposed based on a multi-modulator controller and a neural network. In this method, a neural network is used to adjust the values of the PI controller parameters according to the optimal control rule.…”

STATCOMs is used widely in power systems these days. Traditionally, this converter was controlled using a doubleloop control or Direct Output Voltage (DOV) controller. But DOV controller do not function properly during a three-phase fault and has a lot of overshoot. Also, the number of PI controllers used in double-loop control is high, which led to complexities when adjusting the coefficients. Therefore, in this paper, an improved DOV method is proposed which, in addition to a reduced number of PI controllers, has a higher speed, lower overshoots and a higher stability in a wider range. By validating the proposed DOV method for controlling the STATCOMs, it has been attempted to improve the dynamical behaviors of induction motor using Matlab/Simulink, and the results indicate a better performance of the proposed method as compared to the other methods.
