Abstract

The invention discloses a four-way teleoperation bilateral control method based on time delay compensation. Based on a traditional four-way bilateral control method, by establishing a master-slave endkinetic model and additionally adopting a time delay compensation communication channel, the system stability is ensured, and the system transparency is improved substantially. To solve the problem that a traditional four-way bilateral control method has a destabilization phenomenon on the correspondence time delay condition, a correction wave variable method based on the passive theory is provided, so that the influence on the system transparency by wave reflection of a traditional wave variable is reduced, and the realistic degrees of position tracking performance and force feedback in theteleoperation process are ensured. The stability of a teleoperation system on the time delay condition can be ensured very well, and at the same time, the realistic degrees of the position tracking performance and the force feedback of the slave end are improved. The four-way teleoperation bilateral control method is easy to implement, and can be mainly used for bilateral control on the teleoperation system, and the stability and transparency of the teleoperation system are ensured.

Description

technical field [0001] The invention belongs to the field of remote operation control, and specifically relates to a four-channel bilateral control method of a time-delay teleoperation system, which improves the transparency of the teleoperation system while ensuring the stability of the teleoperation system. Background technique [0002] With the continuous development of robot technology, teleoperation technology relying on human-computer interaction has played an important role in aerospace, deep sea operations, medical surgery and other fields, and has broad application prospects. In particular, the bilateral teleoperation system with force feedback improves the transparency of the system and enhances the operator's sense of presence. However, as the distance between the master and the slave increases, the system will generate a large communication delay during signal transmission, which deteriorates the stability of the system. [0003] In the past, bilateral control g...
