Method for the adaptive adjustment of the control parameters of an electro-hydraulic axis of motion |
摘要 |
The invention relates to a servo hydraulic force controlled system comprising a cylinder, a control valve and a controller as well as a load defining the controlled system. The optimum setting of the controller is automatically performed by using a fuzzy-set-logic, wherein the characteristics of the controlled system must be not known. According to the invention the step response of the controlled system is evaluated with respect to certain geometrical characteristics by means of a fuzzy classificator communicating with a ruling unit which correspondingly varies the control parameters. According to the invention, certain characteristics of the step response are thus used for the fuzzification and the optimizing procedure takes place in a predetermined setting order.
