The invention relates to a robot teleoperation system control technology, and discloses a non-linear teleoperation system position and force tracking and controlling system with time-varying delay aiming to solve the problem of position errors and force errors, caused by transmission delay of position signals and force signals of a driving robot and driven robot, between the driving robot and the driven robot, wherein the transmission delay is generated by time-varying delay of a non-linear teleoperation system. By means of the non-linear teleoperation system position and force tracking and controlling system, system tracking performance is improved, and system stability is guaranteed. According to the technical scheme, the non-linear teleoperation system position and force tracking and controlling system with time-varying delay comprises an operator module, a driving robot controller, the driving robot, a communication channel, a driven robot controller, a driven robot and an environment module. By means of the non-linear teleoperation system position and force tracking and controlling system, the problem of transmission delay, generated through time-varying delay of the non-linear teleoperation system, of the position signals and force signals of the driving robot and driven robot can be effectively solved, and system position and force tracking accuracy is improved.

Description

technical field [0001] The invention relates to the control technology of the remote control system of a robot, in particular to the control system of the remote control system with communication time delay. Background technique [0002] The remote operating system is widely used in deep space, deep sea exploration, minimally invasive surgery, nuclear radiation management, remote rehabilitation treatment and other environmental modules that are difficult for humans to directly reach. Position and force tracking are the most important performance requirements of the teleoperation system, that is, the slave robot must be able to accurately track the position of the master robot, and at the same time, the operator module can accurately obtain the feedback of the interaction force between the slave robot and the environment module. [0003] Since there is usually a certain distance between the physical locations of the master robot and the slave robot, there is inevitably a time...
