Short summary
In this paper, the nonlinear characteristics of the kinematics model of the macro–micro composite actuator are analyzed, the driving force model and kinematics model of the macro-motion part is established, and the model parameters are identified by using the data measured on the experimental platform. The research results lay a theoretical and technical foundation for the development of a high-speed and large-stroke positioning controller of the macro–micro composite actuator.
