摘要

> Modeling physical systems usually results in complex high-order dynamic models. It is often desirable to approximate these models by simpler models with reduced order. The reduced order model retains the desired state variable which contains a significant contribution. A PID controller was designed for the reduced second order model to meet the desired performance specifications by using pole-zero cancellation method. The stabilization of linear discrete time system was achieved by selection of parameters of the PID controller. A numerical example was given to illustrate the design method.
