A Four-Channel Teleoperation Multilateral Control Method for Improved Wave Variables

Abstract

The invention discloses an improved-wave-variable-based four-channel teleoperation multi-side control method. According to the method, the two-side control method is extended to multi-side control; and weight distribution coefficients of a master end and a slave end are designed to realize the multi-side cooperative working function of the system, so that the working efficiency of the system is improved. Besides, a master-slave-end dynamics model is established, a delay compensation communication channel is added, and an ideal transparency condition of the system is proposed, so that the system stability is ensured, the transparency of the system is improved substantially, and the multi-side immediacy sense of the operator is enhanced. In order to solve a problem of instability under the communication delay of the traditional four-channel control method, the invention puts forward a passive-theory-based improved wave variable method; and with two parameters selected independently basedon different needs, a negative effect on the system transparency by the wave reflection phenomenon in the traditional wave variable is reduced and the position tracking performance and force feedbackfidelity of the system during the multi-side teleoperation process are ensured.
