    In their thirteen years of existence, microprocessor chips have evolved through four generations. Contemporary 16-bit and 32-bit microprocessors offer sophisticated architectures and powerful instruction sets. However, in many industrial applications, data rates are very high and the control structure has a decentralized configuration. In either case, multiple processors must be used. The major co...

    The maintainability, reliability, and availability of a computer system are closely bonded to insure continuing service of a system. The ability of a system to tolerate failures or faults while operating is a principal requirement of a fault tolerant system. A fault tolerant system's design must incorporate considerations for maintenance and reliability in order to provide its ultimate requirement... View full abstract»

    A multiprocessor system consisting of three processors built for reliable control of an electrically powered leg (the OSU Monopod) is described. All computations are done in a redundant fashion by two processors. Results are then compared by a different pair of processors, and all three processors participate in the identification of the faulty processor in case of a disagreement of the two sets o...

    A new algorithm is suggested for linear system parameter identification, which lends itself easily to implementation using microprocessors. The main feature of this algorithm is that it is based on the estimation of the values of the successive derivatives of the input and output variables. This new algorithm was successfully used to measure unknown capacitances and inductances together with their... View full abstract»

    This paper describes the simulation of a control scheme using the principle of field orientation for the control of a voltage source inverter-fed induction motor. The control principle is explained, followed by an algorithm to simulate various components of the system in the digital computer. The dynamic response of the system for the load disturbance and set-point variations have been studied. Al... View full abstract»

    The practical and reliable application of direct digital control in industrial systems is a long way from the study of sampling control in modern control literature. Numerous mechanical failures of hydraulic tubes, seals, and mechanical connections have demonstrated that these systems are easily fatigued by ``jitter'' or the type of noise that can arise in digital systems due to quantization of si...

    A system suitable for industrial applications is proposed for the measurement of the area of irregular shapes by scanning the moving object by a photocell-array resulting in a train of pulses each representing 1 cm2, which are totaled and displayed. The measured accuracy of the system is demonstrated to be better than 0.5 percent, typically 0.2 percent, and this is shown to be in good agreement wi... View full abstract»

    A versatile astable multivibrator (VAM) employing a dual timer 556 is proposed. Some of its applications other than the conventional ones, such as voltage-to-period, voltage-to-frequency, voltage-to-time converters, analog divider, and voltage-controlled duty-cycle circuit, are considered. Practical results are in close resemblance with the theoretical predictions. View full abstract»

    A real-time optical sensor has been integrated into a robot end effector. The sensor consists of a four-element position sensing spot, detector and can control a robot motion in two dimensions (two translational axes or translational and rotational axes). Analogical detection and signal analysis ensure fast response of the sensing system. The detecting system has been connected to the ``Unimation-... View full abstract»

    A new kind of extremum control system is described. The system has a single-input controlled process with input and output disturbances and an output lag. The equations of the system are designed in order to follow with a great efficiency the variations of the extremum. The control signal is mainly generated by multiplying the derivatives of the controlled process input and output. In order to eli... View full abstract»

    Transistor dc-dc converters which employ a resonant circuit are described. A resonant circuit is driven with square waves of current or voltage, and by adjusting the frequency around the resonant point, the voltage on the resonant components can be adjusted to any practical voltage level. By rectifying the voltage across the resonant elements, a dc voltage is obtained which can be either higher or... View full abstract»

    This paper shows that the power loss in a thyristor and its commutation circuit can be adequately calculated from a detailed knowledge of the current waveforms and the use of a simple model for conducting thyristors and diodes. In some thyristor circuits, device switching losses can be neglected with little loss in accuracy. Snubber losses are included. The analytical technique described is verifi... View full abstract»
