Speed-dependent setpoint correction in electrically regulated slave drives
摘要:
The system and method of the present invention is to drive a slave axis (S_A) with a value which indicates to said slave axis that the guide axis (L_A) has already rotated further than is actually the case. This can be achieved by adding a correction angle (φcorr) to the measured angle (φL—meas) of the guide axis. In order to configure the virtual onward rotation in such a way that a lag error of the slave axis is just compensated as a result, guide axis angles (φL—meas) are increased by respective correction angles (φcorr) which are proportional to the angular velocity (ωL) of the guide axis and weighted with the data propagation time (TT) of the position measured value (φL—meas) of the guide axis and the delay (TR) of the position control system of the slave axis, said correction angles (φcorr) preferably being dimensioned in accordance with φcorr=ωL*(TT+TR).
