Tracking Control with Zero Steady-state Error for the Discrete-time Mass-Spring-Damper System

This paper is devoted to the tracking control with zero steady-state error (ZSE) for the discrete-time massspring-damper system with external disturbance (DMSDSED). Firstly, the DMSDSED is given. Secondly, based on internal model principle (IMP) and pole assignment, a state feedback dynamic controller is worked out to achieve asymptotic tracking and disturbance rejection for the DMSDSED. In the end, the simulation results show the validity and feasibility of the control method.
