Design of Tracking Control System by Closed-Loop Pole Placement

This paper focuses on designing the MIMO tracking control system which can achieve zero steady state errors and obtain desired dynamic performances, simultaneously.By using state feedback, the closed-loop stability and desired dynamic performances are guaranteed.By integrating the deviations between reference inputs and measured outputs, i.e. augmenting system states, the steady state errors are eliminated.The state feedback gain and the forward integral gain are derived synchronously based on closed-loop pole placement method.Studying results indicate the closed-loop system achieves zero steady state errors and obtains desired dynamic performances as well as closed-loop stability.By pole placement of the closed-loop system combining forward integrator with state feedback controller, a complete tracking control system can be designed.
