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...

Steer-by-wire is the electrical steering systems on vehicles that are expected with the development of an optimal control system can improve the dynamic performance of the vehicle. This paper aims to optimize the control systems, namely Fuzzy Logic Control (FLC) and the Proportional, Integral and Derivative (PID) control on the vehicle steering system using Imperialist Competitive Algorithm (IC...

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...
