Abstract

The invention discloses a switching and controlling method for a moving stage movement mode. The method comprises the following steps that: 1) according to an Euler kinematical equation and a kinematical principle, establishing a kinematical model of a moving stage; and 2) secondly, corresponding to different movement modes to design different control methods. By use of the method, the problem in the prior art that the moving stage can not meet the requirement that curve movement and rotation are simultaneously carried out is overcome, the switching and controlling method for the moving stage movement mode is provided, and the requirement of the diversified display of performing arts can be effectively met.

Description

technical field [0001] The invention is applied in the technical field of stage control, relates to the switching of different motion modes of a mobile stage, and in particular proposes a simple and effective control method for the switching of different motion modes of a mobile stage. Background technique [0002] In modern performances, in order to better achieve artistic effects, it is necessary to control the omnidirectional mobile stage to cooperate with actors to perform. The omnidirectional mobile stage is an omnidirectional mobile platform coupled by four omnidirectional wheels. It is composed of eight motors according to the power and steering control requirements. Each driving wheel has an independent power source, and each axis has a Independent steering mechanism. The mobile stage with this structure has the characteristics of small turning radius and easy turning stability, which is especially suitable for the setting requirements of complex scenes in performan...
