The systematic design of automotive control applications is a challenging problem due to lack of understanding of the complex and tight interactions that often manifest during the integration of components from the control design phase with the components from software generation and deployment on actual platform/network. In order to address this challenge, we present a systematic methodology a...

This paper presents a systematic approach to design a Lyapunov based super twisting differentiator. The differentiator will be shown convergent in a finite time whilst the relevant time is accurately estimated.  This differentiator is the main part to establish the sliding surface in higher order sliding mode. The differentiator  is used in the prescribed control structure  to regulate pressure...

In this paper, an active backstepping design is proposed to achieve control and synchronization of a new hyperchaotic system. The proposed method is a systematic design approach and exists in a recursive procedure that interlaces the choice of a Lyapunov function with the design of the active control. The proposed controller enables stabilization of chaotic motion to the origin as well as synch...

We study multivariable control systems with hard bounded control signals. The reference signals are hard-bounded in their amplitude and speed, which appears in many applications. This description leads therefore to a non-conservative controller design. The design procedure itself is based on H∞Loop Shaping; the problem of systematic adaption on the weights when receiving a too large control sig...

Systematic control structure design requires the use of a model of the plant. Developing rigorous plant models based on physical and chemical principles is often a laborious and time consuming task. This paper studies the effect of simplifications of the heat exchanger model on the resulting control structure design for the PRICO LNG process. It is found that significant model simplifications m...

the intervention of urban design in irans architectural structures has been for many years a challenging issue for architects and urban designers over their professional realm. the preservation of architectural structures in iran has always resorted to extremes. this control and direction has sometimes resulted in exclusion of architecture position and has sometimes, once faced with lack of pro...

background  & aim: case-crossover  studies are the case-control  version of crossover studies. in these studies, cases and controls are the same subjects. the term crossover is applied for designs that all subjects pass through both treatment (exposure) and placebo (non-exposure) phases. in fact they are  crossover  of  subjects  between  periods  of  exposure  and  non-exposure.  this  design ...
