This article presents a method for PID controller design when dealing with stochastic perturbation in first order plus time delay (FOPDT) system. Based on polynomial chaos approach, a computational effective method for analysis stochastic system, one can easily adjust the performance/robustness of system under both stochastic parameter perturbation and additive stochastic input. For validation, the...
An analytical method for the design of PID controller cascaded with the second order lead-lag filter is proposed for the various types of time-delay processes. The proposed design method is based on the IMC-PID method to give a desired closed-loop response. The process dead time is approximated by using the appropriate Fade expansion to convert the ideal feedback controller to the proposed PIDmiddotfilter...
