Abstract Co-simulation is widely used as a powerful tool for performance evaluation of systems design. This approach presents advantages over traditional design methodologies for saving money and time in the development process and the possibility of evaluating rapidly design alternatives by using virtual prototypes. This article presents an ADAMS/Matlab co-simulation for the dynamics and control of a Single-Wheel pendulum ROBot (SWROB) with inertial locomotion actuation to characterize design solutions by means of validation of analytical results. The obtained results by the proposed co-simulation show a significant performance based on the analytical and programming efforts in characterizing and simulating the designed system model. Moreover, open-loop experimental results are presented to validate both the analytical model and the virtual prototype.

In Scandinavia we have for two decades been concerned with participation and skill in the design and use of computer-based systems. Collaboration between researchers and trade unions on this theme, starting with the pioneering work of Kristen Nygaard and the Norwegian Metal Workers’ Union, and including leading projects like DEMOS and UTOPIA, has been based on a strong commitment to the idea of industrial democracy. This kind of politically significant, interdisciplinary, and action-oriented research on resources and control in the processes of design and use has contributed to what is often viewed abroad as a distinctively Scandinavian approach to systems design. This Scandinavian approach might be called a work-oriented design approach. Democratic participation and skill enhancement, and not only productivity and product quality, are themselves considered objective of design. [Based on the two research projects, DEMOS and UTOPIA, I have elaborated this approach in detail in Work-Oriented Design of Computer Artifacts (1989). This paper is based on that work.] Two important features of participatory design shape its trajectory as a design strategy. The political one is obvious. Participatory design raises questions of democracy, power, and control in the workplace. In this sense it is a deeply controversial issue, especially from a management point of view. The other major feature is technical—its promise that the participation of skilled users in the design process can contribute importantly to successful design and high-quality products. Some experiences, perhaps most developed in Scandinavia, support this prediction and contribute to the growing interest in participatory design in the United States and other countries; by contrast, “expert” design strategies have too often turned out to be failures in terms of the usability of the resulting systems. These two features together suggest that there should be a strong link between the skill and product quality aspect of user participation and the democracy and control aspect, or else participatory design will be a deeply controversial issue from the point of view of the employees and trade unions. The trade-union-oriented democracy aspect of skill and participation in design is discussed in the first part of the chapter.

With the emergence of distributed energy resources (DERs), with their associated communication and control complexities, there is a need for an efficient platform that can digest all the incoming data and ensure the reliable operation of the power system. The digital twin (DT) is a new concept that can unleash tremendous opportunities and can be used at the different control and security levels of power systems. This paper provides a methodology for the modelling of the implementation of energy cyber-physical systems (ECPSs) that can be used for multiple applications. Two DT types are introduced to cover the high-bandwidth and the low-bandwidth applications that need centric oversight decision making. The concept of the digital twin is validated and tested using Amazon Web Services (AWS) as a cloud host that can incorporate physical and data models as well as being able to receive live measurements from the different actual power and control entities. The experimental results demonstrate the feasibility of the real-time implementation of the DT for the ECPS based on internet of things (IoT) and cloud computing technologies. The normalized mean-square error for the low-bandwidth DT case was 3.7%. In the case of a high-bandwidth DT, the proposed method showed superior performance in reconstructing the voltage estimates, with 98.2% accuracy from only the controllers’ states.

Research is described which is leading to the specification and development of a motion simulation and design environment for modular robotic systems which enables the implementation of widely applicable software processes for machine control. Current investigation is focused on defining models of application tasks in modular robotic systems. This work is based on the Real-time Control System (RCS) reference architecture proposed by researchers at the National Institute of Standards and Technology (NIST) which was designed to support motion planning and implementation. However, this architecture is modified in such a way that it supports the concept of multitasking and inter-process communication. The emphasis of work is on the hierarchical structuring of solutions, this to enable the design and control of distributed motion elements. Also discussed in this paper is a strategy for achieving sensor-based modularization of modular robotic systems in a manner which facilitates fast and efficient response to changes in the functional or environmental requirements. The paper explains how an application software architecture is unified with the open systems design approach known as Universal Machine Control (UMC), which has been devised and developed at Loughborough University to enable reuse to software and control system components.
