This paper discusses the demands for proper computer aided control system design tools for mechatronic systems and identifies a number of tasks in this design process. It puts the contributions to the session in perspective and describes how the papers in this session (partly) contribute to a solution. Some issues not addressed in the session are discussed and the current state-of-the-art as pe...

This paper discusses the use of control theory for optimum design of aerodynamic configurations. Examples are presented of the application of this msethod to the reduction of shock induced pressure drag on airfoils in two-dimensional transonic flow.

The possibility to control access to data and tools is vital in many organizations where design activities take place. However, in other organizations a stringent access control mechanism would seriously hamper the cooperation among designers. In this paper we present a configurable and unobtrusive access control mechanism for CAD frameworks that is flexible enough to support a wide range of ac...

In this paper, we propose a system-level design method for control systems that enables the development of Hardware-implemented interrupt handler. The increasing complexity of control systems has led to a rise in the frequency of interrupts. As a result, the processor load increases, leading to a deterioration in the latency of interrupt processing. To solve these problems, we require dedicated...

In this paper we discuss collaborative version control issues in a hypertext architecture which has been deened using an agent-level design metaphor. Within this perspective all the basic activities which rule the functioning of the hypertext are formulated in terms of collaborative, parallel mechanisms, which organize global tasks disseminating knowledge and duties over a population of computa...

Axiomatic design is applied to design of real-time control software. As a case study of software design for on-board computers of automobiles, the software of the current anti-lock braking system (ABS) is analyzed based on axiomatic design. It is shown that the current design is a coupled design and that it can be decoupled to improve the performance of the anti-lock braking system software. In...

This paper presents a robust control scheme for flexible link robotic manipulators, which is based on considering the flexible mechanical structure as a system with slow (rigid) and fast (flexible) modes that can be controlled separately. The rigid dynamics is controlled by means of a robust sliding-mode approach with wellestablished stability properties while an LQR optimal design is adopted f...

This paper presents a survey of products of real-time software framework which is composed of software modules for building distributed control systems. This survey mainly deals with the architecture and the design tool of real-time software framework. In addition, it describes the commercial and the academic products of real-time software framework. Finally, this paper compares various product...

In this paper, implicit controls are investigated for different classes of nonlinear systems, nonaffine systems in pure-feedback form and affine systems in strict-feedback form. While control system design for general unknown nonaffine nonlinear systems needs further investigation, elegant control designs are presented for known systems and systems with unknown scalar parametrization. Though fo...
