State Feedback and State Observer

Abstract

In order to improve the performance of the control system, it was needed to design relative controllers and state observers to be suitable for corresponding work conditions for state variables that could depict the each other relationship between inner and outside parameters. Aiming at different performances and conditions, it was needed to know state parameters and to adjust some parameters to make the control system keep a stable state. This chapter mainly narrated state feedback, output feedback and state observer.
