A discrete-time formulation of Cartesian-based iterative learning control with input preshaping method is developed in which partial knowledge of the flexible robot kinematic model is utilized. An advantage of this control method in real implementation is that it does not require the derivative of the end-effector's position, i.e. the velocity of the end-effector. From the characteristics and implementation points of view, it appears to be more attractive than existing control schemes. The convergence analysis is particularly addressed.

A food feeder robot to assist elderly patients to eat food is proposed. A patient can bring the food into his mouth easily by using the man-machine interface with a CRT display and a mouse. The robot has a structure of a 3-DOF arm and a hand with a spoon and fork. A CCD camera is attached to the tip of the robot arm. By using a fabricated 1-DOF robot, the validity of the proposed control scheme using the man-machine interface is confirmed.

Control systems have evolved from local control to centralized control to today's distributed control. With the emergence of fieldbus, new control strategies and architectures using this new concept will revolutionize instrumentation and control systems. The paper discusses the advantages of fieldbus, describe its benefits and impacts on distributed control systems (DCSs) and predict the next architectural transformation of control systems based on the current driving force. Also, some of the technical challenges and three approaches of integrating fieldbus into existing DCSs are presented.

Even though satellite, balloons, and aircraft have served admirably as aerospace platforms for remote sensing and telecommunication, requirements for a new kind of platforms-an easily modifiable, sub-orbital platform-have been widely identified. The High-Altitude Long-Range Observational Platform is a solar power driven LTA vehicle to maintain a station-keeping position in the lower stratosphere for long duration and to carry out missions such as high-resolution, real-time remote sensing, environmental monitoring, disaster evaluation, co-ordination of relief efforts, and high-speed telecommunications relays. Alternative power sources are surface-to-air transmission of microwave energy and high-power laser beams. The authors discuss analytical designs of the platform.

Multilayer feedforward networks have been found suitable for applications in which they need to learn binary-to-binary mappings. We propose a design methodology to simulate sequential functions using neural networks. The combinational function is implemented by a perceptron network with single hidden layer trained using an ETL algorithm. Design of neural storage elements similar to flip-flops is also proposed, which are used as memory elements to store the internal states. Use of the ETL algorithm guarantees convergence for any binary-to-binary mapping, and generally leads to faster convergence than the backpropagation algorithm. The resulting network only consists of neural elements, with all the neurons having integer valued weights and activation thresholds making the network more suitable for hardware implementation using digital VLSI technology.

This paper addresses the problem of scheduling n grouped jobs on m identical parallel machines with objective of minimizing the sum tardiness, subject to the constraints that each model number is only one and has different matching with each machine. A heuristic approach based on list scheduling is presented. Some conditions are presented which can break the sequence of assigning jobs. The results show that it can get a satisfactory solution.

We have designed and constructed a prototype of computer-aided microphone systems with analog devices. It consists of 24 microphone channels. Each is equipped with 47 microphones arranged symmetrically around the array center on each of 4 arcs. By calibrating the mean relative gains and time delays of the microphones used, the experimentally evaluated sensitivity distributions of the constructed system for sinusoidal and band-passed signals of various frequency and bandwidth, and the SNR of the system well coincide with the theoretically expected result, while the relative RMS error of the received signals exhibits slightly large values compared with the theoretical one, which shows the necessity of further compensation of the relative frequency amplitude and time delay characteristics of the microphones used.

We propose a method for realizing separable-denominator two-dimensional transfer function matrices (2DTFM), and we present an upper bound of the realization dimension. Moreover, we suggest that, in the case that the input number is equal to the output number, it is possible that it can be realized with a minimal dimension with respect to both of the two variables. Also, we present two types of state-space realization form. They can be directly obtained from each coefficient of the separable-denominator 2DTFM.

Travel time is a measure of traffic flows in traffic networks and indispensable for the dynamic route guidance system. The queue length and congestion length are described by a nonlinear discrete dynamic system at signalized intersections based on the volume balance. The mean link travel time are analyzed according to the classification of the congestion, offset control and moving direction at downstream signalized intersections in urban traffic networks. The mean link travel time are measured by the average rate of speed of the traffic stream which is one of test-car techniques. The mean link and OD travel time are evaluated for three routes in Fukuyama city according to their analyses. The evaluation values of mean link travel time are compared with the measurement values for each time interval.

The self-tuning speed control of induction motor drives is presented using proportional plus integral (PI) method combined with the recursive least squares parameter estimation method to regulate the motor speed and load variation. To obtain good tracking and control characteristics, a PI self-tuning controller is adopted and the design procedure is developed for systematically finding its parameters according to the recursive least square method. The performance of the PI self-tuning controller greatly improves due to the integral action which eliminate the disturbance and the steady-state error. In addition, the RLS identification minimizes the error between the actual plant parameter and the recently estimated plant parameter.
