The design and improvement of some typical controllers

In the modern industrial control field, the process of measurement and control of the physical variables is fit to the movement rule of classical dynamics and thermodynamics, and the majority controlled systems have the movement performance of classical dynamics, so a criterion controller is designed on the basic of classical dynamics equation; then the paper analyses that PID controller, state feedback controller, robust controller, inner model controller and GPC/MPC controller are identical in classical dynamics. And aiming at the limitation of controllerpsilas algorithm, the paper provides some methods that can improve performances and qualities of control system for control system design.
