Abstract

The invention discloses a washout algorithm-based Stewart platform control method. The method comprises the following steps of S1) obtaining an accelerated velocity of a driver vestibular system; S2)obtaining an instantaneous output accelerated velocity in a translational direction of the accelerated velocity of the driver vestibular system; S3) performing compensation processing on accelerated velocities smaller than a human body threshold in the instantaneous output accelerated velocity; and S4) integrating the input accelerated velocities subjected to the compensation processing to obtainan actual output accelerated velocity in a translational direction of a Stewart platform.

Description

technical field

[0001] The invention relates to the fields of Stewart platform control and the like, in particular to a method for controlling 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 unifie...
