For detection systems that record discrete events, such as particle and nuclear detectors, the dead time is the time after each event during which the system is not able to record another event. An everyday life example of this is what happens when someone takes a photo using a flash - another picture cannot be taken immediately afterward because the flash needs a few seconds to recharge. In addition to lowering the detection efficiency, dead times can have other effects, suc… WebOf course, the best solution is to decrease the many source of dead time in the process and automation system (e.g., reduce transportation and mixing delays and use online analyzers with probes in the process rather than at-line analyzers with a sample transportation delay and an analysis delay that is 1.5 times the cycle time). bgs king kitty value https://histrongsville.com

WebMar 21, 2024 · In , a dead-time-related harmonic minimization method is proposed based on proportional-integral (PI) controller tuning and under the premise of keeping the same control strategy; however, this method cannot completely eliminate the dead-time effect, which still has a great impact on the control system. WebMar 27, 2024 · It is challenging to guarantee the fixed-time stability of the system when it suffers from these constraints. To overcome the above problems, based on the radial basis neural networks and backstepping technology, an event-triggered mechanism is designed to reduce the frequency of control input updates and compensate for the dead-zone input.
