Master end machine-based method for correcting feedback force by force feedback controller

The invention discloses a master end machine-based method for correcting feedback force by a force feedback controller, and aims to solve the technical problems that force fed back to a master end machine is lagged, so that the master end machine moves incorrectly, and a master-slave teleoperation system is unstable. The method is characterized in that force applied by an operator does not need to be measured and estimated, and only the interaction force between a slave end robot and environment, transmitted to the master end machine, and the movement speed of a master end robot need to be determined; the transparency of the master-slave teleoperation system is improved while the teleoperation stability is improved.
