The Inner-outer Loop Feedback Pneumatic Position Synchro Control

It is the key questions that electro-pneumatic synchro system control is difficult to obtain the satisfactory control performance in the synchro system area. Based on the study of the fundamental characteristics of the electro-pneumatic synchro position system with double cylinders, the inner-outer loop feedback synchro controller was designed combining with input-output linearization and friction compensation. To verify the strategies, the experiments in the synchro system were performed. The experimental results show that the new designed controller is effective in both precision and robustness.
