Modeling and Analysis of Harmonic in the Mine Hoist Cnverter Based on Double Closed-Loop Control
In the process of converter driving mine hoist, the output voltage waveform of the inverter is distorted. A novel feedback control method based on the filter inductor current inside loop and voltage is developed in this study. The transfer function model of the two closed-loop control is builded. Parameters of the PID controller are determined through theoretical calculation after analysis of t...

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 اولFrequency control of crane hoist speed
The voltage of the stator is usually controlled with thyristors. To ensure stable control of the load, the control system requires information about the motor speed. Up to now, tachometers or encoders have been used to measure the motor speed, however, tachometers, with their associated equipment, tend to be mechanically sensitive and are often difficult to install, due to space constraints. Th...
متن کاملExpert System Consultation Control Strategy
User interfaces to expert systems represent a bottleneck since consultation time is proportional to the amount of information the system asks the user to supply. An efficient, rather than exhaustive, strategy to direct user questioning will reduce consultation time and effort. An intelligent strategy to minimize questioning, the merit system, has been successfully implemented in Battle, an expe...
متن کاملHoist: A Second-Generation Expert System Based on Qualitative Physics
Hoist system for hypothetical reasoning, Wif models the functionality of all the components, thereby creating a causal model of the Mark 45 lower hoist. This model not only simulates the correct operation of the lower hoist, it also simulates the boundaries of faulty operation. The lower hoist in its actual form (a machine in the real world) is not computer accessible; a computer cannot connect...
