Lambda Tuning Technique Based Controller Design for an Industrial Blending Process

In the present paper, controller design is performed using lambda tuning method and controller performance is compared for various values of desired closed loop time constant. A blending system, which can be represented as a first order plus dead time model, is selected from literature survey for this analysis. The performance is calculated in terms of rise time, settling time, over shoot (%), peak, gain margin, phase margin and closed loop stability. The PID tuning parameters are calculated for performance evaluation. Comparison is performed to select the best value of desired closed loop response time which gives best performance for the selected process model.
