Abstract :
This paper presents the simplest method to design the discrete-time integral servo problem employing PID×(n-2)/2 stage PDA controllers for unstable systems. The results from simulation shown that even the discrete integrator is not introduced the unit impulse responses are easily satisfied differ from the case of continuous-time that necessary to be introduced. In addition, just increasing only the controller gain, the system is robustly stabilizable with the better performance.
