Speech Title: Adaptive Observers for Mechanical and Electromechanical Systems 

Abstract: In this talk we present a new approach to state observation, called Parameter Estimation-based Observers (PEBO) whose main idea is to translate the state estimation problem into one of estimation of constant, unknown parameters. The class of systems for which  is applicable is identified via two assumptions related to the transformability of the system into a suitable cascaded form and our ability to estimate the unknown parameters. The first condition involves the solvability of a partial differential equation while the second one requires some persistency of excitation--like conditions. We present also PEBO in a unified framework together with the---by-now classical---Kasantzis-Kravaris-Luenberger and Immersion and Invariance observers. Morevoer, for systems for which a linear regression-like relation is available, it is possible to combine PEBO with a new estimation technique called Dynamic Regressor Extension and Mixing (DREM). This new technique, called DREMBAO, is used to generate adaptive observers. PEBO and DREMBAO are shown to be applicable to position estimation of a class of electromechanical systems---including motors and MagLev systems---and for speed observation of a class of mechanical systems. 

The performance of these observers is compared with high-gain and sliding mode observers. As expected, it is shown that---in the presence of noise---the performance of the two latter designs is significantly below par with respect to the other techniques.

Speech Title: Traffic Flow Control in a Connected Environment

Abstract: Self- Driving cars are attracting a lot of attention and excitement as they will impact driving comfort and safety as well as modify the current modes of transporting people and goods. Getting rid of the driver however will not necessarily reduce congestion whose main cause is the high volume of vehicles competing in space and time to reach destinations. Connectivity however and compliance to traffic management commands and traffic rules by vehicle autopilots will open the way for far better traffic flow control approaches with strong potential to improve capacity, manage congestion and incidents in a much more effective way.

In this talk, we present several control techniques that can be used to control traffic in a connected environment where vehicles can communicate with the infrastructure. The control techniques involved combined lane change and variable speed control strategies which are analytically shown to effectively control congestion at bottlenecks. Microscopic simulations of traffic in a road network in Southern California near the ports of Los Angeles and Long beach are used to demonstrate the results and quantify the benefits of traffic control.

Title: Smart Control Engineering (SCE) Enabled by Digital Twin

Abstract: Experienced control engineers and researchers agree that before we design a controller we need to ask two questions 1) “What do we have/know?” and 2) “What do we want?” and after we have designed a controller, we also need to ask two questions 1) “How optimal?” and 2) “How robust?” Now, with the emerging wave of “Digital Transformation” such as Industry 4.0, I advocate to ask the third question: “How smart?” This talk suggests a new frontier for control engineering: SCE - Smart Control Engineering and I will show that digital twins (DT) are the enabler towards SCE, a consequence of IAI (industrial artificial intelligence). By “smartness”, following  the notion of US NSF program on S&AS (smart and autonomous systems), we signify the following 5 attributes 1) Taskable; 2) Cognitive; 3) Reflective; 4) Ethical; 5) Knowledge-rich. In this talk, we will show a case study to illustrate the SCE enabled by DT using IAI.

Speech Title: A Robust Model Predictive Control Framework for Intelligent Mechatronic Systems

Abstract: Networked and distributed control for mechatronic systems have received great attention in the control community due to its wide application areas. Network-induced limitations may be caused by the presence of a communication channel, or because of the efficient assignment of power and other limited resources. Intelligent mechatronic systems represent a large class of smart systems that encompass computational (i.e., hardware and software) and physical components, seamlessly integrated and closely interacting to autonomously sense and manipulate the changing state of the physical system. These systems involve a high degree of complexity at numerous spatial and temporal scales and networked communications integrating computational and physical components. Model predictive control (MPC) is a promising paradigm for high-performance and cost-effective control of networked and distributed mechatronic systems. This talk will firstly summarize the major application requirements and challenges to innovate in designing, implementing, deploying and operating intelligent mechatronic systems. Further, the robust MPC and distributed MPC design methods will be presented. Finally, the application of MPC algorithms to intelligent autonomous under water vehicles (AUV) will be illustrated.

Speech Title: Distributed Optimal Traffic Control: Modeling and Synthesis

Abstract: Motivated by the fact that intelligent traffic control systems have become inevitable, and to cope with the risk of traffic congestion in urban areas, a novel distributed control strategy for urban traffic networks is developed. Since these networks contain a large number of roads having different directions, each of them can be described as a multi-agent system. Thus, a coordination among traffic flows is required to optimize the operation of the overall network. In order to determine control decisions, we describe the objective of improving traffic conditions as a constrained optimization problem with respect to downstream traffic flows. By applying the gradient projection method and the minimal polynomial of a matrix pair, we propose algorithms that allow each road cell to determine its control decision corresponding to the optimal solution while using only its local information.

Speech Title: Drone vision for infrastructure inspection and maintenance

Abstract: Infrastructure inspection is one of the most important drone mission tasks. In most cases, long-range and/or local very accurate inspection of the infrastructure is needed, e.g., for bridges, road infrastructure or electrical installations. Various inspection modes are overviewed, e.g., visual inspection, thermography and 3D imaging (LIDAR), focusing on faulty object detection. Furthermore,   infrastructure maintenance activities based on aerial manipulation involving force interactions are presented. Finally, aerial co-working safely and efficiently helping human workers in inspection and maintenance is overviewed. To this end, human-centered computing, e.g., human pose estimation, action recognition are needed.
