[0002] Optical switches, especially electrostatically driven MEMS optical switches, are widely used in the fields of optical fiber transmission and optical fiber testing due to their advantages of small size, simple structure and fast response speed.

[0003] In order to obtain the ideal response speed, control algorithms are usually used to control optical switches, such as direct open-loop control of step voltage, input shaping control and sliding mode control algorithms. The traditional control method is to first develop a hardware system for a specific optical switch, manually program and debug the code according to different algorithms, but the hardware system cannot meet the electrostatic drive requirements of most optical switches, thereby increasing the control cost of the optical switch. In addition, various errors are prone to occur in the process of manual code writing, making the debugging process difficult and time-consuming.

[0004] The prior art CN111176196A discloses a control system and a control method for an optical switch. By providing a larger DC power supply for the optical switch, the problem of needing to develop specific hardware control systems for different electrostatically driven MEMS optical switches is solved, thereby reducing production costs. By constructing an algorithm through graphical programming based on simulink, the code can be automatically generated and downloaded to the system, thereby eliminating the need for manual code writing and avoiding various errors that may occur in the process of manual code writing, making the debugging process difficult and time-consuming.

[0005] However, the control system and control method of the above optical switch cannot perform efficient and intelligent control on multiple optical switches simultaneously, so that each optical switch needs a separate control system for control, thereby increasing the equipment cost of the control system of the optical switch.
