We define a Byrnes-Isidori form for a class of infinite-dimensional systems with relative degree r and show that any system belonging to this class can be transformed into this form. We also analyze the concept of (stable) zero dynamics and show that it is, together with the Byrnes-Isidori form, instrumental for static proportional high-gain output feedback stabilization. Moreover, we show that...

Evaluative adjectives like stupid, smart, silly, and rude have been recognized as a coherent syntactic and semantic class for over forty years (Lees 1960, Bolinger 1961, Vendler 1963, 1968, Quirk et al. 1985). The class has gained recent attention, however, from syntacticians looking to extend analyses of argument alignment in the verbal domain to the adjectival domain (Stowell 1991, Bennis 200...

In this paper, an adaptive sliding mode disturbance observer is designed to counteract the actively. By designing laws, assumptions on are relaxed in proposed observer, its first derivative upper bound considered be unknown. Based output feedback controller constructed for continuous-time linear systems with unknown external disturbance. The incorporates only system information and has less cha...

Due to growing importance of wireless access and the steeply growing data volumes being transported, the power consumption of wireless access networks will become an important issue in the coming years. This paper presents a model for this power consumption and investigates three base station types: macrocell, microcell, and femtocell base stations. Based on these models, the coverage effective...

We study a control system which includes several impulse modulators employing some kind of frequency modulation. It is shown how to chose periodic external actions in order to ensure the existence of a synchronous periodic mode, i.e. of such a mode that all the modulators emit impulses with the same frequency. 1 Problem Setting We consider an asynchronous impulsive system with m impulse modulat...

in this paper, an adaptive neuro fuzzy sliding mode based genetic algorithm (anfsga) controlsystem is proposed for a ph neutralization system. in ph reactors, determination and control of ph isa common problem concerning chemical-based industrial processes due to the non-linearity observedin the titration curve. an anfsga control system is designed to overcome the complexity of precisecontrol o...

This paper presents a new adaptive Sliding-Mode flux observer for speed sensorless and rotor flux control of three-phase induction motor (IM) drives. The motor drive is supplied by a three-level space vector modulation (SVM) inverter. Considering the three-phase IM Equations in a stator stationary two axis reference frame, using the partial feedback linearization control and Sliding-Mode (SM) c...

The goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. The effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. This is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...
