This article concerns the complete controllability for nonlinear neutral impulsive stochastic integro-differential system in finite dimensional spaces. Sufficient conditions ensuring the complete controllability are formulated and proved under the natural assumption that the associated linear control system is completely controllable. The results are obtained by using the Banach fixed point the...

Wepresent techniques for rendering implicit surfaces in different pen-and-ink styles. The implicitmodels are rendered using point-based primitives to depict shape and tone using silhouettes with hidden-line attenuation, drawing directions, and stippling. We present sample renderings obtained for a variety of models. Furthermore, we describe simple and novel methods to control point placement an...

This paper presents a new approach to robust control of a real multilink flexible manipulator via regional pole assignment. We first show that the manipulator system can be approximated by a linear continuous uncertain model with exogenous disturbance input. The uncertainty occurring in an operating space is assumed to be norm-bounded and enter into both the system and control matrices. Then, a...

This paper is mainly concerned with feedback control systems governed by fractional impulsive evolution equations involving Riemann–Liouville derivatives in reflexive Banach spaces. We firstly give an existence and uniqueness result of mild solutions for the equations by applying the Banach’s fixed point theorem. Next, by using the Filippove theorem and the Cesari property, a new set of suffici...

The robust control problem concerns to the control of plants that are only approximately known. Usually, it is assumed that the plant lies in a set of possible plants and this set can be quantitatively characterized. It is sought a control design that assures some kind of performance, which includes stability, for all the members of the family of candidate plants. Robust control theory usually ...

The proposed method is situated within the actual trend of integrated process control design. The paper deals with a modern research theme in plantwide control field. Within this framework, it tries to solve the problems concerning the operation of distillation columns, many of these problems deriving from design errors of control structure. Analyzing from plantwide control point of view the pl...
