Integral error based controller design & performance analysis for a TOPDT process

In present analysis, the selected third order plus dead time process model is converted in to first order plus dead time model using Skogestad and Taylor's series approximation techniques. Proportional integral (PI) controller for the first order with time delay process have been designed using integral error based tuning rules viz. Integral of the absolute value of the error, Integral of the time weighted absolute value of the error, Integral of the square value of the error, Integral squared time weighed of the error and Integral squared time-squared weighted error criterion. These controllers are then compared for their set point tracking capability.
