Abstract

The invention discloses a multilateral adaptive sliding-mode control method for a nonlinear teleoperation system. Based on a radial basis function neural network, the method estimates the non-power environment parameters of slave environmental dynamics to transmit to a main end to perform main end environmental force reconstruction through a communication channel; for the nonlinear and various uncertainty problems of master-slave robots, the method respectively designs trajectory builders on the main and slave ends and a radial basis function neural network based nonlinear adaptive sliding-mode controller and also designs the online training adaptive rate of a nonlinear function including system modeling information, so that the stability and accurate position tracking performance of a system can be guaranteed; and for signal communication problems between multiple robots, the controlling force distribution of multiple slave robots can be realized by designing a collaborative force allocation algorithm, and therefore, the collaborative operation performance of the multiple robots on work tasks can be enhanced.
