This paper presents a generalized dynamic observer design for polytopic quasi–linear parameter‐varying systems where the parameters are depending on unmeasured state variables. It generalizes the existing results on the proportional observers and proportional‐integral observers. Conditions of existence and stability are given through the Lyapunov approach. Its design is obtained in terms of a set...
Various studies describe the magnetic excitation generated by coils, however the electromagnetic component is present when using this type of device. For this reason, the objective of this article is to present a system of magnetic excitation of low magnitude and variable frequency that does not include the electromagnetic component.
Undoubtedly, research and development activities in higher education institutions must have scientific, technological, social and economical impact in the surroundings. However, since the researcher's productivity in Mexico is measured by the number of publications, the results seldom conclude in a true technological development. This paper describes the result of an initiative between Morelia Institute...
Minimally invasive surgery demands the development and maintenance of the specialized surgeon's psychomotor skills. These skills can be measured objectively through hybrid and virtual training systems. Of which, the most advanced, integrates force feedback systems and augmented reality graphics. However, these systems are inaccessible because of their high cost, limiting the expected academic impact...
Due to recent tendencies to optimize the use of the discharge lamps and the pollution problem caused by mercury, this paper outlines a simple approach that puts the reuse of tubular fluorescent lamps into perspective. The operation of the lamp is through dielectric barrier discharge which is powered using short pulses voltage. A Class-E converter, which is suitable for dielectric barrier discharge,...
