In the present paper, a fuzzy logic based ultrasonic motor (USM) is used in order to properly control the speed and phase difference for the elasticity and viscosity of a robot joint. The traveling wave USM is driven by two-phase sine wave signals, and the phase difference of the signals is usually selected to +90/spl deg/ and -90/spl deg/ meaning high speed and maximum torque of the USM. In this paper, we describe USM rotational speed characteristics at no load. The first phase difference is adjusted in the range from +90/spl deg/ to -90/spl deg/ by fuzzy controller as is the reached target speed.

This paper presents an adaptive hybrid control approach for a robot manipulator to interact with its flexible object. Because of its flexibility, the object dynamics influence the robot’s control system, and since it is usually a distributed parameter system, the object dynamics as seen from the robot change when the robot moves. The problem becomes further complicated such that it is difficult to decompose the robot’s position and contact force control loops. In this paper, we approximate the object’s distributed parameter model into a lumped ‘position state-varying’ model. Then, by using the well-known nonlinear feedback compensation, we decompose the robot’s control space into a position control subspace and object torque control subspace. We design the optimal state feedback for the position control loop and control the robot’s contact force through controlling the resultant torque of the object. We use the model- reference simple adaptive control strategy to control the torque control loop. We also study the problem on how to select a reasonable reference model for this control loop. Experiments of a PUMA robot interacting with an aluminum beam show the effectiveness of our approach. © 1996, VSP and Robotics Society of Japan.

A hybrid system is a system containing both of time-evolving components and event-driven components. A formal approach is explored in this paper, based on Extended Duration Calculus (EDC), for the development of hybrid systems. A typical example of hybrid system from modern control theory, a two-level adaptive control system, is used for illustrating our approach. Its high level consists of an event-driven supervisor which reacts to the change of plant structure, and its time-evolving low level consists of adaptive controllers and other components. Firstly performance specifications and system specification of the case are formulated in EDC;then they are refined stepwise into specifications of the supervisor and the low level components. Our approach emphasizes the interface between the two kinds of components in the hybrid system. © Springer-Verlag Berlin Heidelberg 1994.

In this paper, we describe the fault tolerant schemes for the multistage interconnection network (MIN) and its fault diagnosis. Firstly, we present a fault tolerant MIN and a adaptive self-routing scheme for the network. It can provide more multiple paths than the previous networks between an input/output pair of a network by adding extra links between switching elements in the same stage and modifying the self-routing scheme of the regular MIN. The presented routing scheme is as simple as that of the regular MIN, which is based on the topological relationships among the switching elements (SE’s) that render a packet to the same destination with the regular self-routing. We present an algebraic proof to show the correctness of the scheme, and an analytic reliability analysis to provide quantitative comparisons with other some networks. Of the special notes is the finding that the network is more cost effective than the regular MIN and other augmented MIN’s in terms of the reliability. Secondary, we consider the fault models in the fault detection and the location schemes. We present a new fault diagnosis scheme for the network. © 1994, Springer Verlag. All rights reserved.

In this paper, we study the performance of a prioritized on-board baseband switch in conjunction with a multibeam satellite handling integrated services. The services considered for the analysis include voice, video, file transfer and interactive data. The prioritized switch uses both input and output buffering, switch speed-up as well as a two-phase head-of-line resolution algorithm, in order to reduce the buffer loss while maintaining acceptable user delays. The minimum required buffer capacity and switch speed-up for each service in a prioritized environment are found under uniform traffic conditions. It is shown that under uniform traffic conditions, only minimal buffering and switch speed-up are needed even for the lowest priority users. The performance dependence on the switch size is also substantially reduced with head of line resolution and buffering even in a prioritized environment.
