Trajectory Generation of High Rise/High Speed Elevators
The problem of generating the trajectory for high rise/ high speed elevators is investigated in this paper. Several approaches are used: open loop optimal control, closed loop optimal control and optimization algorithms. Each approach is accompanied by numerical simulations.
متن کاملRobust Tracking for High Rise/High Speed Elevators
Jing Li David Niemann Hua O. Wang Department of Electrical and Computer Engineering Duke University, Durham, NC 27708, U.S.A Abstract This paper deals with control design for the motion control of high-rise/high-speed elevators. Two main problems, tracking and releveling, are treated in the framework of output regulation problem. By doing this, we design a single controller satisfying both perf...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEfficient electricity production portfolios taking into account physical boundaries
In this paper the efficiency of the electricity generation portfolio of BKW, a major Swiss utility, is analyzed. By applying mean-variance portfolio theory to the current and to possible future generation mixes, efficient frontiers are derived. The analysis based on relative changes in generation costs is complemented by an actual costs analysis. Moreover, a method that takes into account physi...
متن کاملPower Consumption Reduction in High-Speed ΣDelta Bandpass Modulators
Power consumption is a key point in the design of high-speed switched capacitor (SC) circuits, which allow to efficiently implement a number of analog functions. Among them, SC Σ∆ modulators are very popular for A/D conversion: in this kind of circuits, operational amplifiers are the most consuming cells because of their requirements in terms of DC gain and unitygain frequency. A new amplifier ...
