Problems like windup or rollover arise in a PI controller working under saturation. Hence antiwindup schemes are necessary to minimize performance degradation. Similar situation may occur in a Proportional Resonant (PR) controller in the presence of a sustained error input. Several methods can be employed based on existing knowledge on PI controller to counter this problem. In this paper few su...

In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator. We use a combination of the addition and inclusion methods to mask the information. The performance of two observers, the proportional observer (P-observer) and the proportional integra...

this paper presents a novel control approach used in shunt active power filter based on variable structure control combined with random pwm technique (rvsc) that provides robust, fast, and more favorable performance for active power filter. this control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
