Open vs closed loop control system
The principal drawback of open-loop control is a loss of accuracy. Without feedback, there is no guarantee that the control efforts applied to the process will actually have the desired effect. If speed and accuracy are both required, open-loop and closed-loop control can be applied simultaneously using a feedforward … Ver mais Continuing the analysis, it is clear that all closed-loop operations are not alike. For a continuous process, a feedback loopattempts to maintain a process variable (or controlled variable) at a desired value known … Ver mais For a discrete process, the variable of interest is measured only when a triggering event occurs, and the measure-decide-actuate sequence is typically executed just once for each event. For example, the human … Ver mais Many automatic control systems use both open- and closed-loop control in parallel. Consider, for example, a brewery that ferments and bottles … Ver mais Open-loop controllersdo not use feedback per se.
