    The large increase in traffic density during the last 25 years in the US, Europe, and Japan has required the automation of some functions of traffic control and monitoring. Buried magnetic loops are widely used for this purpose, but there are functions such as incident detection, vehicle tracking, etc., which are not implementable with them. In addition, magnetic loops are not flexible. Image proc... View full abstract»

    A new method for detecting fluctuations in the fundamental frequency component of a power system, by relating it to a leakage coefficient in the FFT, is presented. The phenomenon of leakage in the FFT is used advantageously to increase spectral resolution. The leakage coefficient is a quantitative measure of the deviation from the fundamental frequency component with respect to the sampling freque... View full abstract»

    A digital speed control system for a dc motor with a pulse tachogenerator for speed sensing is described. A microprocessor is used for fast speed measurement with a response time constant of the order of 8 ms and a resolution of 0.0125 percent of the top speed. This has become possible because of the principle of obtaining the latest speed value based on the previous speed value. This paper descri... View full abstract»

    The paper describes new methods of detecting rotor position in stepping and switched motors, with chopper or series-resistance drives, by monitoring winding currents. In contrast to previous methods of waveform detection, the new techniques are reliable over the complete speed range. It is shown that the most useful indicators of rotor position are: i) current rise times arising from chopping an u... View full abstract»

    Pulsewidth modulation (PWM) control of brushless dc motors is implemented with digital servo mechanisms for robotic applications. Under the assumption that the pulse period is much smaller than the motor time-constants, the motor is modeled by a discrete-time transfer function with the pulsewidth playing the role of the control signal. This model enables the application of classical linear control... View full abstract»

    This paper describes methods of calculating current references for ministepping step motor controllers. An implementation based on piecewise-linear interpolation from motor characteristic curves is presented. This method takes into account motor nonlinearities. Ministepping accuracy so obtained is compared with those of other controllers. View full abstract»

    Quality assurance has been of a great concern in the process of resistance spot welding, since considerable variation in the weld quality often arises even when the machine variables are held constant. In this paper a new microprocessor-based control method is developed to obtain uniform weld quality regardless of the changing welding environments. The control system utilizes a proportional (P) co... View full abstract»

    Sliding mode control is an effective means to keep a system insensitive to parametric variations and disturbances. In the conventional sliding mode control applied to position servo systems, the sliding mode regime is restricted near the origin, and, therefore, insensitivity cannot be ensured throughout an entire response. This paper presents a new method in which a sliding curve is used instead o... View full abstract»

    Many industrial applications require the use of multiple computing elements. The overall performance of such multiprocessor systems is a strong function of the communication capacity of the interconnection bus. By increasing this capacity one can integrate more processors, memory units, and input-output devices together and obtain a higher overall system throughput. In this paper, an analytic mode...
