Abstract:
PID control is the most common control method used in automatic control. Aiming at the second- order time- delay systems of industrial process control, a method for the fast calculation of all stable PI controllers via plotting stability boundary locus in kp- ki is presented. Moreover, the necessary conditions are proposed for the ex istence of a PI controller to simultaneously stabilize the second-order time- delay systems that are open- loop unstable. Furthermore, the set of PI controllers satisfied with the performance specifications requirements of a controller design is easily to work out via searching on the stabilizing region. An example is given to show the effectiveness of the method presented and the paper provides a simple and effedive method for controllers design.
