Dynamic Modeling of Automatic Machines for Design and Control

本書描述了自動機器的設計經驗及其控制的理論背景。與現有文獻不同，本書包含了設計概念及其與自動化設備動態行為的關係，並將機器元件的動態響應與構成自動機器的驅動裝置聯繫起來。因此，本書展示了正確地將任何自動機器建模為一個整體系統的重要性，並尋找最終響應以獲得良好的設計和控制方案。引言部分描述了設計自動機器的背景、其在機器設計中的獨特性，以及理解動態行為的必要性。接下來的章節提供了多體系統建模的背景、典型自動機器的範例，以及確定最常見驅動裝置（電動機、氣動和液壓活塞及閥門）動態響應的基礎。第四章描述了在自動機器中使用的最常見傳感器的動態響應，而第五章則包括了將驅動裝置與最終效果（針對每個特定應用的專用工具）連接的機器元件的動態模型。最後幾章包含了不同自動機器的動態模型範例，涵蓋了影響最終響應的所有元素，並描述了模擬技術（及其在範例中的應用）以及轉移函數在估算自動機器瞬態響應中的應用。

After more than 30 years of experience, Dr. Jauregui has demonstrated the effectiveness of designing automated machines for improving life. The philosophy behind his work is finding processes that reduce wasting time, energy, and materials. Most of his developments are installed in different manufacturing companies in Mexico and abroad; they include simple devices up to high-precision multifunctional equipment. One of the most significant development was the robot for positioning the secondary mirror of the Large Millimeter Telescope (located in the State of Puebla in Mexico). For the automobile industry, he developed precise automated machines for a specific process, combining the technical requirements with the inclusion of low-cost labor operators. The design concepts improved productivity and product quality, keeping the global market competition. One of the strengths of his work was the ability to create project management strategies that ensured the design specification's accomplishment in time and fulfilled the user's expectations. The technology developed in the design of the tailor-made automatic machines was promoted in different forums, publications, and open discussions with colleges worldwide.

He also has worked in designing and operating wind turbines and solar concentrators. The wind turbines are installed at Universidad Autonoma de Queretaro and have a double purpose: being a research laboratory and a training facility for young engineers. The design of the wind turbines was the basis for graduating Ph.D. students in many topics around this equipment. It also contributed to international collaboration with universities in the USA. The technology developed with these machines covers areas such as aerodynamics, structural design, component design, speed control, integration to the grid, and Conditioning Monitoring, among others.

From a theoretical point of view, Dr. Jauregui has worked on developingmonitoring systems based on vibration measurements. His primary interest is in interpreting the vibration signals for predicting the remaining life of mechanical systems. He has studied different signal analysis techniques, such as the Continuous Wavelet Transform, the Hilbert-Huan Transform, the space domain, and statistical methods, such as the Hurst coefficient and the Approximate Entropy. His research on these topics has been published in journals, conference proceedings, and books. This work backed up his students' graduate thesis and was the research topic for international cooperation with universities in Hungary and Italy.

His research work granted some of his distinctions, such as the highest level among the National Research System (Mexico). He chaired the Technical Committee for Vibrations at IFToMM and is currently a member of its Executive Committee. He is a Fellow Member of ASME and chairs the Technical Committee of Wind Energy at the International Gas Turbine Institute (ASME). He is also a senior member of the IEEE. He has been the President of the Mechanical Chapter of the National Engineering Academy (Mexico) and a founder member of the Mexican Society of Mechanical Engineering.

He works to educate future engineers from a holistic perspective. He is looking for future work that will contribute to reducing the social differences around the world and ensure that the natural resources will be there for the next generations.

胡安·卡洛斯·哈烏雷吉-科雷亞（博士）

在超過30年的經驗中，哈烏雷吉博士展示了設計自動化機器以改善生活的有效性。他工作的哲學是尋找能夠減少時間、能源和材料浪費的過程。他的大部分開發成果已安裝在墨西哥及國外的不同製造公司中，涵蓋從簡單裝置到高精度多功能設備的各種產品。其中一項最重要的開發是為大型毫米波望遠鏡（位於墨西哥普埃布拉州）設計的次鏡定位機器人。對於汽車產業，他開發了針對特定過程的精密自動化機器，將技術要求與低成本勞動力操作員的納入相結合。這些設計概念提高了生產力和產品質量，保持了全球市場的競爭力。他工作的優勢之一是能夠創建項目管理策略，確保設計規範按時完成並滿足用戶的期望。針對量身定制自動機器的設計技術在不同的論壇、出版物和與全球學院的公開討論中得到了推廣。

他還從事風力發電機和太陽能集中器的設計與運營。這些風力發電機安裝在克雷塔羅自治大學，具有雙重目的：作為研究實驗室和年輕工程師的培訓設施。風力發電機的設計為許多與該設備相關的博士生畢業提供了基礎，並促進了與美國大學的國際合作。這些機器所開發的技術涵蓋了氣動力學、結構設計、元件設計、速度控制、並網整合和狀態監測等領域。

從理論的角度來看，哈烏雷吉博士致力於基於振動測量的監測系統開發。他的主要興趣在於解釋振動信號，以預測機械系統的剩餘壽命。他研究了不同的信號分析技術，如連續小波變換、希爾伯特-黃變換、空間域和統計方法，如赫斯特係數和近似熵。他在這些主題上的研究已發表在期刊、會議論文和書籍中，這些工作支持了他學生的畢業論文，並成為與匈牙利和意大利大學進行國際合作的研究主題。

他的研究工作為他贏得了一些榮譽，例如在墨西哥國家研究系統中的最高級別。他曾擔任國際機械工程師學會（IFToMM）振動技術委員會的主席，並目前是其執行委員會的成員。他是美國機械工程師學會（ASME）的會士，並擔任國際燃氣渦輪學會（ASME）風能技術委員會的主席。他也是IEEE的高級會員。他曾擔任墨西哥國家工程學院機械分會的會長，並是墨西哥機械工程學會的創始成員。

他致力於從整體的角度教育未來的工程師。他尋求未來的工作，以幫助減少全球的社會差異，並確保自然資源能夠留存給下一代。
