A LMI-based approach is proposed to design a quadratically stable flux observer for an induction motor. The resulting observer is a parametrically varying dynamic system that insures a L2-gain attenuation between the exogenous input and the flux estimation error of the augmented plant. Its performance is evaluated and compared with those of the Verghese observer.
This paper investigates the so-called extended stabilization control problem for continuous-time descriptor systems. In such nonstandard stabilization problem, the generalized plant and its unstable and/or nonproper weights are all described within the descriptor framework. The extended stabilizing controller (ESC) is sought such that: -The closed-loop is admissible;- Only the internal stability of...
This paper investigates the design of an “extended” H2 output feedback controller for continuous descriptor systems. In such problem, the controller, which is described within descriptor framework, has to satisfy simultaneously two conditions: 1-The closed-loop is admissible and has minimum H2 norm. 2-Only the internal stability of a part of the closed-loop is sought. In such case, the standard H2...
The use of an Electrical narrow tilting car instead of a large gasoline car should dramatically decrease traffic congestion, pollution and parking problem. The aim of this paper is to give a unique presentation of the geometric modeling issue of a new narrow tilting car. The modeling is based on the modified Denavit Hartenberg geometric description, which is commonly used in Robotics. Also, we describe...
