“…First loop was used to keep the DC capacitor constant, while the second loop were used to extract the reference source currents [36]. Second, the type I fuzzy logic were used as an adjuster to tune the PI controller in the double-loop control strategy [37]. Third, the fuzzy logic controller used to change the proportional and integration gains in the respect of the load changing instantaneously.…”

The interval type II fuzzy logic controller (IT2FL) is a recent artificial intelligent technology which is applied in many aspects of electrical power engineering and controlling strategies these days. The improving of Distribution Static Synchronous Compensator (DSTATCOM) control algorithms is still ongoing, because the control strategy of DSTATCOM device is considered as a decisive factor which affects the performance of DSTATCOM device in enhancing the quality of power in the distribution grids. The improving process focuses in two main aspects the DC capacitor voltage response to the control system and the mitigation of the harmonics which are produced by the controlled and uncontrolled rectified loads. In this paper, the interval type II fuzzy logic controller (IT2FL) based the Unit Voltage Template strategy (UVT) is examined by the MATLAB program with two different ranges of input signals, and compared with the type I Fuzzy logic controller (T1FL). The IT2FL based UVT shows promising results in improving the deformed shape of source current waves in comparison with the other controllers.

“…Mehtn and Schauder [7]presented a Conventional Double-Loop Control Strategy. In this method, there are two loops; the external loop of the active and reactive current generates the reference current for maintaining the voltage at the PCC point, and the internal loop is used to control the inverter current [8].…”

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.
