| Popis: | The paper presents the challenge of finding the best criterion in selecting adequate control algorithm for electro-hydraulic actuator with a defined load. The ideal control algorithm that adapts to the actual configuration of electro-hydraulic actuator and defined load is used as an initial assumption. Atypical flexible load that is viscose-elastic, with a significant level of hysteresis that also depends on time and temperature is considered as well. Two types of load modeling approaches are proposed, accompanied by presentation on how load modeling options affect the actual response of an actuator system. The main disturbance, in this case, is considered to be external force generated by thrust force real oscillations. |
