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...
The dynamic behavior of many systems can be approximated by a linear model at each operating point. Therefore, if the process works in several operating points, a set of linear models can be constructed to represent the system behavior. Those multi-models can be viewed as a system with random uncertain bounded parameters with definite influence over the behavior of the solution. Stability and performance...
