Diagnostyka. 2018;19(2):95-103 Jadavpur University, bipantudu@gmail.com 5 Jadavpur University, rb@iee.jusl.ac.in Abstract Blast furnace operation requires highest quality raw materials, operation and operators. Among them coke is the most important, in terms of its effect on operation and hot metal quality. A good grade coke produces highest thermal energy and it is highly efficient in case of metal reduction. Usage of good grade coke to blast furnace will ensure lower coke rate, higher productivity and lower hot metal cost. In order to concentrate the free atmosphere. There is need to automate the coke oven operations as much as possible. In order to improve the level of control and management of coke oven, the research on intelligent control system is carried out. In modern advanced control system of coke oven, the control scheme of combination, feedback & feed-forward merged with management are widely utilized. The integrated management and control system of coke oven is introduced systematically, including the production plan and scheduling management (Dynamic scheduling) & heating control system (Mathematical modeling) i.e. evaluating battery temperature, intelligent combustion control and pressure control of gas collector of coke oven battery.

“…Because of its phase coherent start regarding a received FMCW radar chirp signal the SILO can be used as an active backscatter transponder in a secondary radar system [1]. The designed SILO is based on a cross-coupled topology as previously published in [2] and optimized to achieve a high output power of 14 dBm and fast turn-on times.…”

“…An active backscatter transponder based on a SILO is attached to life vests and used as a key component for round-trip time-of-flight (RTOF) measurements [1]. With the help of an unmanned aerial vehicle (UAV) circling around the emergency area the exact position of the passenger can consequently be calculated through distance measurements and triangulation [2].…”

This paper presents a novel combination of two fully integrated phase-locked loops (PLLs) to control the oscillation frequency and modulation frequency of a switched injectionlocked oscillator (SILO). The SILO is used as an active reflector transponder in a frequency-modulated continuous wave (FMCW) radar system. A fractional-N PLL (RF-PLL) with a tri-state phase-frequency detector (TSPFD) sets the oscillation frequency of the voltage controlled oscillator (VCO) to 2.45 GHz. Another integer-N PLL (modulation PLL) switches the tail current source of the VCO to achieve SILO behavior at the time when the RF-PLL is not controlling the VCO. The RF-PLL supports division ratios from 64 to 511 with a frequency resolution of 0.2 Hz. Reference spur levels are below -48 dBc while the outof-band phase noise is -103 dBc/Hz at a 1 MHz frequency offset. The modulation PLL is based on a Maneatis-cell ring-oscillator supporting modulation frequencies between 6 MHz and 20 MHz. Furthermore, the duty cycle of the modulation signal can be set in steps of 0.8 %. Due to the novel TSPFD, the oscillation frequency of the SILO changes only by 36 MHz within 10 minutes when the RF-PLL is inactive. The complete circuit is manufactured in a 180 nm SiGe BiCMOS process and consumes a total power of 128 mW.
