The open loop system is also known as "no feedback system". Symmetry of "closed loop system (feedback system)". The system's input affects the output of output instead of output. Because there is no closed feedback loop in which the closed feedback loop is formed, it is as disconnected. Since the output does not impose an impact on the input, the open loop system does not respond to the output deviation and the disturbance, and only specifically responds to the set value. For example, a clock is a open system because it does not observe it on time or not, it will not adjust itself. There are few open-loop systems in the socio-economic system. In the initial stage of system dynamics model debugging, the designer can cancel the feedback loop so that the system is an open-loop system to simplify the problem, easy to debug.
Open loop control, also known as "open loop control system" refers to a control system that is not affected by the input signal of the system in a control system. That is, the results of the control result are not referred to in the current controlled system.
Mae'r rheolaeth dolen agored yn golygu mai dim ond y ddyfais reoli a'r gwrthrych rheoledig sydd yn y broses reoli yn unig heb gyswllt gwrthdro. Felly, nid yw allbwn y system rheoli dolen agored yn effeithio ar reolaeth y system. Mae rhai dyfeisiau awtomeiddio ar gyfer gwahanol adrannau'r economi genedlaethol, megis peiriannau gwerthu, peiriannau golchi awtomatig, llinellau cynhyrchu awtomatig cynnyrch, turnau awtomatig, ac ati, yn systemau rheoli dolen agored yn gyffredinol.
Gan fod y rheolaeth agoriadol yn cael ei nodweddu, dim ond un ffordd yw'r ddyfais reoli a reolir gan signal mewnbwn penodol, ac nid yw'n mesur y swm rheoledig ac mae gwrthdroi yn effeithio ar y rheolaeth, nad oes ganddo gywiriad oherwydd aflonyddwch Y gallu a achosir gan wyro faint o reolaeth oddi wrth y gwerth a ddymunir.
Mewn rheolaeth dolen agored, ar gyfer pob signal mewnbwn o'r system, rhaid bod cyflwr gweithio sefydlog a swm allbwn system. Gan fod cynhwysedd gwrth-aflonyddu rheolaeth dolen agored yn wael, mae cyfyngiad ar y defnydd.
