In this paper, the authors analysed a cycling phenomenon of a real control system. As the results, after some experiments we came to the conclusion that this phenomenon was caused by a backlash in the pneumatic controller. Carrying out the analysis of the control system including this non-linear characteristic by means of the gain-phase plane, it was found that the cycling frequency and amplitude were nearly in agreement with the experimental results. By the gain-phase plane the cycling should occur when the proportional sensitivity of a Paction controller is 19.0 db, but by our experiments it occurred when the proportional sensitivity is 18.5 db. The larger the sensitivity is, the larger the frequency and amplitude of cycling.
