Control method of two-translation and one-rotation three-degree-of-freedom platform

The invention relates to the field of automobile maintenance equipment, in particular to a control method of a two-translation and one-rotation three-degree-of-freedom platform, which is used for solving the control problem of centering rotation variable parameters of the platform and specifically comprises the following steps of: establishing a platform mechanism system; and reversely calculating the variable quantity of the telescopic ejector rods of the three groups of driving mechanisms corresponding to different positions of the movable platform in a trigonometric function operation mode, and controlling the linear motion mechanisms of the three groups of corresponding driving mechanisms to continuously operate through the multi-axis motion controller so as to realize the control on the rotation accuracy of the movable platform. The method has the advantages that the hardware structure is simple, and the reliability is high; and the control algorithm is easy to realize and has better popularization value
