Patent DE-4103441-A1 (DE)
Title: Increasing electrically controlled drive position regulator target accuracy - by doubling gain for each step in which control value is below minimum value
Inventor: GEITNER GERT-HELGE DR ING
IPC: G05D3/14
Filed: 1991-02-01
Abstract: The method of increasing the target accuracy of a position controller with a subordinate revolution rate controller, whereby the position controller is a p-controller, involves doubling the gain (Vrx) of the position controller, starting from a dynamically required value (Vrxdyn), for each step when the control value (Nsoll) has fallen below a min. value. The position controller's gain factor is limited to the value 1. When the demanded position value changes again the original gain factor is used again. USE/ADVANTAGE - For use with electrically controlled drives. Simple control algorithm makes full use of resolution of position measurment element with simple, automatic optimisation.
