Abstract

The invention discloses a control system of a Stewart platform based on a washout algorithm. The control system comprises a data acquisition system and a data processing system. The data acquisition system is in data connection with a game or a visual system and used for obtaining instant output accelerated speed of a translational direction of accelerated speed of a vestibular system of a driverfrom the game or the visual system and obtaining the distance from the center of an upper platform of the Stewart platform to a brain vestibular system. The data processing system is electrically connected with the data acquisition system and used for compensating accelerated speed, less than threshold value of a human body, of the instant output accelerated speed and integrating input acceleratedspeed subjected to compensation operation in order to obtain actual output accelerated speed of the translational direction of the Stewart platform.

Description

technical field [0001] The invention relates to the fields of Stewart platform control and the like, in particular to a control system of a Stewart platform based on a washing-out algorithm. Background technique [0002] Stewart platform parallel mechanism has the characteristics of high rigidity, strong bearing capacity, and non-accumulation of position errors. It complements the series mechanism in application, and has become a research hotspot in space mechanics. At present, Stewart platform parallel mechanisms have been widely used in aviation, aerospace, subsea operations, underground mining, manufacturing and assembly and other industries. Although a large number of research results have been achieved in the practical application and theoretical research of parallel mechanisms, there are still some challenging problems in kinematics, singularity, and dynamics, such as the solution of the Jacobian matrix of parallel mechanisms with few degrees of freedom. A unified met...
