Closed-Loop Turbulence

Open loop control system Definition


The open-loop control of reactor is considered through an optimization problem to compute surfactant and CTA feed flow rates to achieve the desired bimodal PSD and MWD.The realisation of an advanced, integrated open-loop control system for a baggage conveying system is not possible without a stable, high-performance network.They are primariy relya-regulated, with open-loop controls on the injection process.The widely used open-loop control of injection velocity has been shown not to work well, and the injection velocity dynamics have been experimentally shown to be nonlinear and time-varying.Open-loop control of shuttle movement cannot compensate for process changes such as oil-temperature variations, and thus requires some reduction in speed to avoid hitting the mechanical stop.Parison control provides four separate 100-point profiles per parison card, selectable interpolation methods, and closed- or open-loop control.Easy-to-use, open-loop control and leak-resistant clamp cylinder are two key features.Previously the nozzle was available in a low-voltage, open-loop control configuration.In the near future, the TC-40 may tie new pmT (pressure-mass-temperature) software for optimizing the holding-pressure phase directly into its open-loop control.It also provides closed- or open-loop control of injection, 15 zones of PID temperature control, and data-logging to disk, printer or host computer.It provides open-loop control of four independent control functions.
