However, generating good job shop schedules in a reasonable time remains a challenging problem, because of its inherent computational complexity. Dynamic job shop scheduling (DJSS) has been proven to be an intractable analytical problem and is largely solved by combinatorial analysis in traditional research. The NP-complete nature of the problem forces many assumptions to be made, which limit the use of analytical methods in practical problem solving. In this paper, the authors propose a new scheme named minimum queuing delay (MQD) for scheduling in a dynamic job shop derived from fair queuing service disciplines for asynchronous transfer mode (ATM) networks. This scheme combines the job process-time and work-content of jobs in the current queues into the dispatching methodology. The main advantage of this scheme is that the queuing delays suffered by all the jobs at every machine are minimized, leading to a minimized maximum completion time (make-span). A smaller queuing delay variation is also achieved using this algorithm. Results from experiments conducted on a testbed with several embedded controllers are presented.","PeriodicalId":378710,"journal":{"name":"IECON'99.

The method overcomes the limitations of classical feedforward neural network-based approaches via applying uniform structures derived from the Euler-Lagrange equations in the most general and formal level. Being a compromise between the classic hard computing (HC) and soft computing (SC) the typical difficulties as the a priori unknown number of the necessary nodes and free parameters, the scaling problems regarding the applicable range of the parameters are evaded. On this basis a relatively simple uniform structure of reduced number of parameters appropriate for real time tuning can be obtained. Several ancillary procedures also independent of the details of the particular task to be solved are applied to support machine learning, too. The operation of the method is illustrated via simulation in the case of a 3 active and one passive DOF SCARA arm used for polishing the surface of a bell-shaped work-piece.","PeriodicalId":378710,"journal":{"name":"IECON'99.

However, presence of the air gap flux harmonics gives rise to undesirable torque pulsations. These torque pulsations result in performance deterioration in high-performance drive applications. In this paper, we present a systematic way to design and implement a new instantaneous torque controller using discrete iterative learning control (ILC) scheme with the objective of achieving torque ripple minimization. In the proposed scheme, the ILC-based dynamic torque controller compares the desired and the instantaneous motor torques and generates the reference q-axis current (i/sub qs_ref/) that is required to produce ripple-free torque. The instantaneous motor torque is estimated by using an estimator based on MRAS technique. The proposed ILC torque controller is simple to implement from a computational point of view. The effectiveness of the proposed torque controller is demonstrated through computer simulation studies and results obtained verify the effectiveness of the proposed scheme.","PeriodicalId":378710,"journal":{"name":"IECON'99.

CL and photoluminescence (PL) measurements are discussed on the background of the formation of nanoclusters in the open cages of the zeolite host structure. DAF was mixed with a SnCl/sub 2/ solution and subsequently dried under stirring and annealed in H/sub 2/- or O/sub 2/-ambient to establish metallic Sn or semiconducting SnO/sub 2/ clusters in the zeolite pores. Samples with various nominal weight ratios were prepared, i.e. SnO/sub 2//DAF=0.15-0.8 and Sn/DAF=0.1-0.6. X-ray powder diffraction (XRD) analysis shows that the nominal incorporation of Sn or SnO/sub 2/ resulted in weak reduction of the lattice constants. At 77 K all samples exhibit a strong CL signal in the blue spectral range, which was clearly visible by the eye, but no significant spectral properties which might be attributed to a nanocluster formation could be deduced. PL measurements at 77 K do not give significant verification of a cluster formation, too. One can conclude that the strong CL mainly originates from the DAF and that the incorporation of Sn or SnO/sub 2/ clusters was either rather poor and/or has no significant influence on the luminescence behavior.","PeriodicalId":378710,"journal":{"name":"IECON'99.
