 note = {Elevator is widely used in our daily lives to carry passengers or transport belongings in the rising buildings. However, the motion performance of the elevator is strongly affected by load changes and nonlinear air damping. In this paper, to address these issues, the design of a digital acceleration control method is described. First, a dynamic model of an elevator is derived with consideration of load changes and nonlinear air damping. Then, a digital controller is designed based on the derived dynamics, and the parameter of the elevator is identified by using the control torque and the output acceleration signal. The digital acceleration controller is a special controller to deal with the load changes and nonlinear air damping for its control force contains the gravity force of the load and the nonlinear air damping. Finally, simulations are conducted, and the results demonstrate the effectiveness and usefulness of the proposed control method.},
