| Abstract: | This paper studied digital control of fatigue testing machine for catenary accessories. A self- optimization control scheme was presented, Parameters of digital controller was optimized by itself, and non-linear elements of process was compensated. The gain of control system would self-alternate according to the stiffness of specimen, Evaluation of resulting controller showed that it occurred to design the performance gaols of 2 % specimen load accuracy while providing hundreds different kinds of specimen with different stiffness. |
