An analytical tuning method was proposed for fuzzy PID controller used in Smith predictor in order to extend its application and improve its robustness. The fuzzy PID controller was expressed as a sliding mode control. Based on Lyapunov theory, Smith predictor was analyzed in time domain. The parameters of the fuzzy PID controller can be obtained using traditional linear control theory and sliding mode control theory. The simulation experiments were implemented. The simulation results show that the control performance, robustness and stability of the fuzzy PID controller are better than those of the PID controller in Smith predictor. 展开更多

He was an influential living Buddha (Renpoche) in Tibetan Buddhism and a talented and legendary historical figure. Nowadays, more and more scholars, poets and translators have devoted to the study of his works. Here we will focus on discussing the English translation of his poems and their value. We analyze texts of the Tsangyang Gyatso's Poems (Chinese-English) and seek to further study the translation principles such as "retaining truth, seeking goodness and preserving beauty". By doing this, we strive to improve the quality of translation, give consideration to the construction of the four elements such as poetic meaning, emotion, tone and intention, to enable the reader to achieve the senses and the acquisition of images, to provide more perfect translation in the "Tsangyang Gyatso Vogue", to promote the dissemination and sharing of Tibetan culture and to inject new vitality. 展开更多

Through such process, buildings are occupied by new usages that assure they are not abandoned. However, conservation issues, like pathological manifestations by filamentous fungi, are common even in buildings receiving new uses. Thus, it is extremely important to know the microclimate behavior of these buildings and analyze if there are usages that favor the appearance of filamentous fungi or not. This study aims to verify if new usages modify the microclimate in historical buildings and if such possible change favors the appearance of pathological manifestations by filamentous fimgi in some specific use. To achieve the results, three buildings that have gone through recycling processes were chosen in the city of Pelotas, in Southernmost Brazil. The city possesses a large number of buildings with historical value and its climate conditions are propitious for appearance of filamentous fungi. For 12 months, microclimate was monitored, the environments modus operandi was characterized and there was a survey on the pathological manifestations by filamentous fungi in the three buildings with two different uses: administration offices and exhibition rooms. Conclusion was that usages that allow natural ventilation and lighting favor conservation, which is what happens in the ones used as administration offices. Besides that, it was noticed that the construction system also influences, since buildings with a high cellar that is being used did not present filamentous fungi, which also shows the influence of ascending humidity on the appearance of such pathological manifestations. 展开更多
