The convergence of socio-economic factors, workforce composition, accelerating product obsolescence and technological advances has created an unparalleled need and fertile opportunity to redefine the workforce model. These new technological capabilities alone are insufficient to reinvent the business models. Management must, through vision and solid commitment at all hierarchical levels, migrate its values, reinvent precepts, coalesce processes, and redefine its workforce models to remain financially viable in the emerging compressed timelines. The tools are at hand; economic realities make corporate change a financial requirement; and the changing values, goals and social composition of the workforce apply pressure to create a new, network centric workforce model. These converging pressures make rethinking the corporation viable and necessary. How rapidly these changes occur will be determined now by old-fashioned rates of human I corporate acceptance of change. Compression of the market timeline may force significant, perhaps unrecoverable fallout among those companies that are slow to take up this challenge.","PeriodicalId":171131,"journal":{"name":"Proceedings of the IEEE 2000 National Aerospace and Electronics Conference.

In standard direct fuzzy controller, utilization of the rule-base is mostly poor, especially when error input gets smaller and the control action is produced by only a few rules in the center of the rule-base. With such a small number of rules, the fuzzy controller performs inadequately because the resulting control surface can capture very approximate control actions. This poor utilization of the rule-base may degrade the controller performance. A possible solution to this problem may be to redesign the rule-base such that the rule base has move rules at the center. However, this solution limits the ability of the controller to a limited input range and specific inputs. Instead, a DFL fuzzy controller is proposed, which ensures that the fuzzy controller can utilize the entire rule base by auto-tuning algorithm. Computer simulation and experimental results on a 5 hp induction machine are presented to substantiate the proposed scheme.","PeriodicalId":171131,"journal":{"name":"Proceedings of the IEEE 2000 National Aerospace and Electronics Conference.

Implementation of roll motion in magnetic suspension wind tunnel 磁悬浮风洞中横摇运动的实现

The development of magnetic suspension wind tunnel (MSWT) is designed to free the model from conventional mechanical supports. Under precise model design, a roll motion with appropriate control can be implemented in MSWT. This paper presents a modification of NCKU 10 cm/spl times/10 cm MSWT to accomplish the roll motion control in wind tunnel tests. The modification of this experiment includes position and attitude sensing and test model design. The position and attitude sensing is improved and set-up by a laser-optical circuit, quadrant detectors and dual-lateral detector in x-axis to ensure accurate measure. The rolling inertia is generated from a rotating mass inside the test model. With very careful design, a rocket model is fabricated for experiments. A passive PID control is implemented to achieve the predictable constant roll motion on the test model. A current feedback loop is applied to strengthen the control stability. Being different from other MSWT applications, the test model is locked by the position and attitude sensing via feedback control loop. Due to the accomplishment of motion test roll only constant speed in good control limitations, demonstrates performance. The idea of this study is to extend dynamic test capability in the magnetic suspension wind tunnel, and bring further valuable applications.","PeriodicalId":171131,"journal":{"name":"Proceedings of the IEEE 2000 National Aerospace and Electronics Conference.

The power supply system of the tracker, described in this paper, has been constructed optimizing noise performances, following space qualification criteria for a ten day mission on the shuttle and considering the operation in the fringe magnetic field of the spectrometer. This paper also includes a short description of tracker electronics. Optimisation and qualification tests on the complete power supply system are reported.
