Abstract

The invention discloses a four-side fixed support plate vibration anti-interference composite sliding mode control system and method, and aims to solve the problem of buffeting caused by interference resistance in a sliding mode vibration control process due to complex boundary conditions of a fixed support plate, model uncertainty and external unknown excitation interference in the four-side fixed support plate vibration anti-interference composite sliding mode control system based on model design. In order to solve the problem of complexity of a control algorithm developed by taking a code as a core at present, a composite sliding mode vibration control system combining an extended state observer ESO and sliding mode control is designed based on an NI PCIe model.

Description

technical field [0001] The invention relates to the technical field of vibration control systems, in particular to a vibration-anti-interference composite sliding mode control system and method for a four-sided clamped plate. Background technique [0002] The four-sided clamped plate structure has the advantages of light weight and high rigidity. Due to these advantages, it has been widely recognized in the fields of aerospace, automobiles and ships. However, there are various disturbances and uncertainties in the industrial process, which can easily cause vibrations of different amplitudes of the structure, resulting in fatigue damage to the clamped plate structure, reduced service life, structural damage, affecting the service life of the product and reducing the user's experience. Even threaten the safety of users' lives. Therefore, the four-sided clamped plate is of great significance in the field of vibration control. [0003] In order to improve the vibration suppres...
