A Predictive Proportional + Integral (PPI) controller with improved performance over standard PI and PID controllers is proposed. This controller consists of two parts : a standard PI controller and a predictive term with which its dynamics depend on the system time delay. The controller is realized by a continuous time implementation; i.e. a numerical solution of differential equations rather than a transformation to the Z-domain. The performance of this controller is compared with that of the PID controller tuned by Zeigler and Nichols and three other recent methods of tuning PID controllers. The conditions for stability are derived and the sensitivity of the new controller to process parameter changes is analysed by Monte-Carlo evaluation.
