Self-Adjusting Feedforward Compensation Tracking Control for Proportonal Valve-Controlled Motor

摘要

Aiming at the position tracking control for valve-controlled motor electrohy- draulic proportional servo systems mainly driving the static load torque, the tracking perfor- mance was studied in the presence of the variable gain and deadzone. Methods on the basis of coventional composite control with the deadzone compenstion method, a comprehensive con- trol approach with the deadzone and self-adjusting feedforward compensation was proposed.
