Description
| KC is a tuning variable of the current loop. For compensation of time delay a predicted current value can be used in addition to the measured motor current. KC 1 switches the current prediction on, KC 0.5 sets it to 50% and KC 0 switches it off. Disabling the current prediction can cause an unstable current loop. Depending to function FILTMODE KC selects different algorithms . By setting FILTMODE=1 (Default) the usually prediction is used, with setting FILTMODE =2 the Smith Predictor is switched on. If the Smith Predictors is on the proportional gain of the current controller MLGQ can increase, in case the settings ML and MRS are tuned well . |
