2、theapplication of the new type of PID algorithm on electro-hydraulic proportionalposition control system was researched. Based on the principle of the new type PIDcontrol algorithm, the tracking effects on sine signals were compared between thenew PID control and the conventional PID control through
3、 experiments. The resultsshow that the new PID control than conventional PID control have better accuracyand stability.Key words: new PID control;electro-hydraulic proportional valve; position control;PID control0PIDPIDPID1likuWPDF-XC hangeww.docu -track.cmCctobyNO!PDF-XC hangeww.docu -track.co名师资料总
