Control of Uncertain Systems: Modelling, Approximation, and Design: A Workshop on the Occasion of Keith Glover’s 60th Birthday

This can be a selection of articles via pals, co-authors, colleagues, and scholars of Keith Glover, Professor of Engineering on the collage of Cambridge, at the get together of his sixtieth birthday. Professor Glover's paintings spans a number of subject matters, together with process identity, version relief and approximation, strong controller synthesis, and regulate of plane and engines.

Predictive Functional Control: Principles and Industrial Applications

The calls for of the trendy economic system have resulted in a dramatic bring up within the business program of model-based predictive keep watch over ideas. in truth, except PID, predictive keep an eye on is one of the hottest keep watch over procedure in use at the present time. The predictive practical keep watch over (PFC) procedure was once first used to enhance a model-based predictive controller that used to be effortless to appreciate, enforce and music from an instrumentation engineer’s point of view.

8 Fig. 6. 4 Results and Discussion 17 Case 1, case 2 and case 4 can be combined to a single case of “critical distortion line” that to be discussed in the next section. Case 3 is not necessary because the interest here is distorted inlet propagation. The affecting parameters should involve only that of the inlet conditions. The compressor should be considered as a given geometric domain. As to the asymptotic behavior situation, case 5, there is much further work to do, which will be mentioned next also.

2 Inlet Flow Condition As an example, consider a situation of air-to-air refueling when a leakage of fuel enters the engine nacelle together with the inlet air. Some of the smaller droplets of leakage fuel vaporize and form a vapor-air mixture. When this mixture reach the fan blade or first stage of compressor with temperature of about 15 °C (much higher value if past the IGV) during refueling, the mixture may well be within the range of flammability, especially for the more volatile wide-cut fuel.
