Embodiment 3
[0136] As a better alternative, the difference between this embodiment and Embodiment 2 is that: the cable arrangement system is an optical fiber screening machine cable arrangement system, and the cable take-up device is a cable take-up reel 4 . For fiber screening machine wiring system, please refer to image 3 Shown, utilize the method in embodiment 2, see Figure 4 As shown, the control block diagram of the optical fiber screening machine wiring system can be obtained. The traditional fiber optic screening machine wiring system uses mathematical calculations to calculate the speed relationship between the rotating motor and the translation motor, which belongs to open-loop control. After a certain period of error accumulation, there will be wiring problems (the wiring is too dense or sparse) . In this embodiment, by listing the time-domain and frequency-domain equations and deriving the theory of Lyapunov's second method, the open-loop control is changed into a closed-lo...
