It is important to consider diagnostic coverage (DC) of the automatic diagnosis (AD) scheme in course of the design of highly reliable systems in which redundancy technique is usually applied. Considering the nature of AD is to introduce some form of redundancy, its performance will be affected by common cause failure (CCF). Due to that diversity is an effective antidote for CCF, it is desirable to...
Safety Instrumented Systems (SIS) are automatic systems designed for the purpose of taking an action to avoid an accident or minimize its consequences. Safety Instrumented System relies on many devices that must work as designed at a specific point in a hazard scenario to stop propagation of the hazardous event. Safety Programmable Logic Controller (PLC) plays a more and more important role in the...
Generally the application of traditional adaptive control algorithm relies on the mathematic model of system. But mathematic models of some dynamic systems are difficult to establish. According to this actual problem and the existing structure of algorithm, an improved Model Free Adaptive control algorithm based on neural network is put forward in this paper. Within corresponding controller, equivalent...
