    This paper presents the methods of design and control for a coupled tendon-driven robot hand with stiffness control capability. By using the tendon as a force transmission mechanism, compact design of the robot hand is achieved with the developed controller. Problems specific to the tendon characteristics are considered, such as the slacking problem of tendons when the joint is disturbed, and the ... View full abstract»

    This paper discusses the use of acceleration measurements to improve the performance and robustness of controllers for mechanical systems. To use acceleration signals there are at least two approaches: direct use in a feedback loop to improve the tracking error, and indirect use by an observer to improve the estimates of position and speed. Several proposals for the use of the acceleration in a fe... View full abstract»

    Vacuum pan crystallization is a process that is very difficult to control by classical means. This paper presents a method of using a rule-based expert system for the control of such a process. The structure of the expert controller for adjusting the characteristic conductivity is shown to consist of a diagnostic expert system and a discrete dynamic model that is used for conversion of semantic re...

    In the last 10-15 years, control of paper variation in the cross machine direction has become a necessary requirement to meet increasing quality demands. Traditional approaches to the control of weight, moisture and caliper have realized good reductions in paper profile variability using relatively simple control technology. Recent advances in computer technology have provided the platform to impl... View full abstract»

    The linear algebraic method for designing control systems was introduced in the Magazine (Cen,1987, and Chen and Seo, 1990). In this article, the method is compared with designs using Q-parameterization and then compared with designs using pole-placement and model (pole-and-zero) matching. It is shown by an example that the method may also yield a better result than the quadratic optimal and the H... View full abstract»

    Frequency response analysis is a classical method for obtaining models of linear, time-invariant systems. However, the quality of the results strongly depends on the experiment design and choice of parameters. Likewise, different problems may demand a fault diagnosis. This article presents a knowledge-based system that guides the user through the planning and execution of a frequency response expe... View full abstract»

  • Motivation-by challenge for teaching control systems

    Publication Year: 1994, Page(s):64 - 68

    An unconventional, motivation-by challenge approach is reported for teaching entry-level control courses. This approach recognizes the difference between passive learning and active learning, and therefore emphasizes motivating entry-level students with a pilot design project that is woven into lectures from beginning to end.<> View full abstract»
