IBERO organized the 1st International Workshop on Active Disturbance Rejection Control
Dr. Mario Ramírez Neria, Dr. Zhiqiang Gao, Dr. Eduardo Gamaliel Hernández Martínez, Dr. Hebertt Sira Ramírez y el Dr. Jorge Ángel González Ordiano
Last Wednesday, July 3, the 1st International Workshop on Active Disturbance Rejection Control kicked off at the Iberoamericana University (IBERO) Mexico City, a space that seeks to promote Research in the field of Active Disturbance Rejection Control (ADRC), bringing together leading researchers, academics, and graduate students from around the world to collaborate, exchange and share theoretical and empirical research findings, as well as innovative applications of this field.
Members of the Organizing Committee: Dr. Mario Ramírez Neria, researcher at the Institute of Applied Research and Technology (InIAT IBERO); Dr. Zhiqiang Gao, from the Center for Advanced Control Technologies at Cleveland State University; Dr. Hebertt Sira Ramírez, from the Center for Research and Advanced Studies (Cinvestav) of the National Polytechnic Institute (IPN).
As well as Dr. Jorge Ángel González Ordiano, director of InIAT IBERO, and Dr. Eduardo Gamaliel Hernández Martínez, Director of the Division of Science, Art, and Technology at IBERO, attended the opening ceremony and gave a brief talk to attendees focus in the relevance of this first workshop in automatic control to IBERO, its students and Mexico.
Dr. Mario Ramírez Neria, master of ceremony, indicated different activities, such as face-to-face and virtual sessions, discussions, coffee breaks, etc. Experts from countries such as China, Poland, Colombia, Mexico, and some parts of the United States will present their Research and work abstracts during the event.
"These events help us to strengthen ties with universities and to generate new collaboration agreements to do Research and thus attract undergraduate students to do their Master's degree or PhD. So that they can apply later to obtain interchange student programs, visit other universities, and complement their studies."
Dr. Ramirez explained that ADRC is a control technique that estimates external disturbances. It was developed to control industrial, robotic, and other mechatronic processes, which require a very detailed process to track trajectories or remain at a desired set point despite external disturbances commonly found in these kinds of processes".
"Industrial processes are critical in the industry; they must be exact. ADRC reduces the complexity of applying the control laws for these systems and becomes robust. This algorithm has grown a lot and is today at the top of Research worldwide."
For his part, Dr. Eduardo Gamaliel said that in recent years IBERO created a new group of academics in dynamics and control systems in the Departments of Engineering and InIAT.
"We are interested in applying new control strategies to solve issues, such as assistance robots for people with disabilities, therapy, and others. We are always looking for alliances with other universities, research centers, and companies. So this workshop is an important step in IBERO's collaboration with Cleveland State University and CINVESTAV-IPN, especially with our guest of honor, Professor Zhiqiang Gao and Professor Herbertt Sira being the global representatives of the ADRC with many years of experience in the field."
Dr. Eduardo Hernández revealed that Dr. Mario Ramirez brought the first ADRC projects to IBERO and that, despite not being an expert, he is sure that ADRC has shown potential to solve several academic and industrial problems.
"Given the growing potential in the actual application of ADRC and its importance, it is relevant to develop theoretical and practical projects on this topic. I would like to express my gratitude to all the people who made this event possible and the Direction of Continuing Education of IBERO for their support."
OVERVIEWActive disturbance Rejection Control ADRC as originally proposed by J. Han has three components: tracking differentiator, nonlinear feedback control, and nonlinear extended state observer. The combination of the three proves to be a powerful tool for disturbance rejection control. As an industrial control technology, however, it has been streamlined, simplified and parameterized so that it can be easily deployed across various hardware-software platforms and easily tuned by factory personnel, leading to explosive growth in its applications that transcend engineering disciplines. ADRC is accomplished and married as advanced principle into a domain of engineering applications that often leads to an order of magnitude improvement. Most importantly, it will be shown in this workshop that the key in application of ADRC is the reformulation of the control problem as that of disturbance rejection, as shown in applications in several key technology areas such as internal combustion, power generation, space applications, aeronautics, process control, and high energy physics |
