There are a variety of directions in which mobile payments can go. We could see merchants continuing to opt for closed loop systems, or we could see open-loop mobile wallets emerge as the preferred choice. But the evolution of mobile payments will likely not transpire with a clear winner. More likely is the coexistence of these options.
The open loop system is called the non-feedback system while the closed loop is the feedback system. The control and controlled process are the two components of the open loop system. The closed loop requires some components likes an amplifier, controller, controlled process, feedback system etc.
There are now tools and methods that enable one to safely optimize and tune PID loops in closed loop mode and with the right understanding, it is possible to optimally tune every PID loop in a plant with minimal time and risk. Traditional methodology for optimizing and tuning PID loops (excluding ‘trial-and-error’) rely on ‘open-loop’ tests, whereby the loop is placed in manual mode
Sistem di motor injeksi sendiri terbagi dalam dua kategori, yang dikenal dengan istilah open loop dan close loop. "Perbedaannya ECU sistem injeksi close loop menerima input berupa data Air Fuel Ratio (AFR) di saluran gas buang dari sensor O2, sedangkan open loop tidak," jelas Rizky, Service Advisor Clara Motor, Kebon Jeruk, Jakarta Barat. The blue line is when certain closed-loop components are applied to the op-amp. Bandwidth is normally measured at the 3dB point of the frequency response and in the case of an op-amp (open-loop) this will be at 24Hz in the diagram. If closed loop components were present, the gain would be reduced to (say) 20dB (blue line) but the bandwidth
Thus the system automatically corrects any changes in output. Hence it is a closed-loop system. Example 2: Traffic Control System Open Loop System example: Traffic control by means of traffic signals operated on a time basis constitutes an open-loop control system. The sequence of control signals is based on a time slot given for each signal.
