Abstract

The invention provides a control device and a control method of a hydraulic vibration active isolation platform. The control device comprises a control computer, an A / D (analog / digital) data process card A, an A / D data process card B, a D / A (digital / analog) data process card, a signal modulator A, a signal modulator B, a power amplifier, an acceleration sensor A, an acceleration sensor B and a displacement sensor, wherein one acceleration sensor A, one acceleration sensor B and one displacement sensor are mounted on each hydraulic active operation rod of the hydraulic vibration active isolation platform; the acceleration sensor A is mounted on the top part of an inner cylinder of the hydraulic active operation rod; and the acceleration sensor B is mounted on the top part of an external cylinder of the hydraulic active operation rod. The control device has strong expanding property; types and number of the data collecting cards are increased by modifying a control module; a plurality of similar vibration isolation platforms are conveniently and simultaneously controlled; and vibration isolation functions of the platform are realized under the environments of large amplitude, low frequency and heavy load.

Description

technical field [0001] The invention relates to a control device for a hydraulic vibration active isolation platform and a control method thereof, belonging to the technical field of structure / mechanism active control. Background technique [0002] With the wide application of technologies such as data relay and high-resolution observation, the demand for high-stable and precise tracking and aiming mechanisms has become increasingly urgent. Vehicle-mounted or airborne high-performance optical equipment and laser equipment, as typical tracking and aiming mechanisms, should have high pointing accuracy and vibration control capabilities, and active vibration isolation control is an effective technical approach to provide vibration control capabilities. Active vibration isolation refers to introducing a secondary vibration source into the disturbed system, and adjusting the output of the secondary vibration source through an effective control method, thereby offsetting the distu...
