Load Simulator

An electro-hydraulic load simulator (EHLS) is a typical case of torque systems with strong external disturbances from hydraulic motion systems. A new velocity synchronizing compensation strategy is proposed in this paper to eliminate motion disturbances, based on theoretical and experimental analysis of a structure invariance method and traditional velocity synchronizing compensation controller (TVSM). This strategy only uses the servo-valve's control signal of motion system and torque feedback of torque system, which could avoid the requirement on the velocity and acceleration signal in the structure invariance method, and effectively achieve a more accurate velocity synchronizing compensation in large loading conditions than a TVSM. In order to facilitate the implementation of this strategy in engineering cases, the selection rules for compensation parameters are proposed. It does not rely on any accurate information of structure parameters. This paper presents the comparison data of an EHLS with various typical operating conditions using three controllers, i.e., closed loop proportional integral derivative (PID) controller, TVSM, and the proposed improved velocity synchronizing controller. Experiments are conducted to confirm that the new strategy performs well against motion disturbances. It is more effective to improve the tracking accuracy and is a more appropriate choice for engineering applications.

The article is devoted to the analysis of economic and financial problems and contradictions accumulated in Latin America under conditions of globalization and market liberation. The originated unfavorable changes gave rise to the need of policy correction in big and small countries. The author analyses a new strategy of development adequate for Latin America with its specific geopolitical situation, demographic structure and history.

This article explores new political practices of the Roman Catholic Church by means of a close critical examination of the beatification of the Martyrs of Cajonos, two indigenous men from the Mexican village of San Francisco Cajonos, Oaxaca, in 2002. The Church’s new strategy to promote an upsurge in canonizations and beatifications forms part of a “war of images,” in Serge Gruzinski’s terms, deployed to maintain apparently peripheral populations within the Church’s central paternalistic fold of social and moral authority and influence, while at the same time as it must be seen to remain open to local cultures and realities. In Oaxaca and elsewhere, this ecclesiastical technique of “emplacement” may be understood as an attempt to engage indigenous-popular religious sensibilities and devotion to sacred images while at the same time implicitly trying to contain them, weaving their distinct local historical threads seamlessly into the fabric of a global Catholic history.
