  • Abstract
    In this paper, system identification algorithm of an electro-hydraulic system for feedforward position control method is proposed. Feedforward controller using inverse model of feedback system generates filtered signals that compensate the magnitude and phase. In this manner, the feedback system has been properly identified. We estimated the system as linear discrete time transfer function by recursive least squares algorithm. The real-time experiment is conducted by NI-CompactRio and Labview, and MATLAB/Simulink for the validation of suggested method.
