Automated Maximum Sensitivity And Phase Margin Specification Attainment In Pi Control

Abstract: The prevailing industrial and academic autotune paradigm uses the relay experiment to find the ultimate data of an unknown system, followed by the use of this data in PI (D) tuning rules. This paper firstly reviews a novel method of obtaining desired frequency response data‐points of an unknown system which is more accurate and flexible than the relay experiment. The paper then demonstrates how this new identification module can be used in closed loop to automate PI controller tuning to achieve classical robus… Show more

“…Diseño robusto de controladores PI con base en la sensibilidad máxima M S , y el margen de ganancia A m (Crowe and Johnson, 2002). Optimización simultanea del desempeño ante cambios en el valor de consigna y la perturbación, con una restricción en la robustez (M S ≤ 2,0), utilizando algoritmos genéticos para controladores PID Estándar de 2GdL (Shen, 2002).…”

“…Since the main objective of the proposed method is to assess the maximum sensitivity and stability margins of a compensated system, it is useful to investigate the assessment accuracy achievable with the method. To this end, a group of processes with dynamics representing a wide range of those encountered in the process industry 8,13 is used in a simulation study to assess the accuracy of the parameters thus identified.…”

“…Example 1. Consider a high-order process with delay, The PI controller used to control the system is described by Following the procedures adopted Section 2.2, a |λ|−φ curve is generated (Figure ) and the maximum sensitivity ( M s ), gain margin ( G m ), and phase margin (φ m ) are identified as 1.85, 2.65, and 1.09, respectively. The desired maximum sensitivity ( M̃ s ), gain margin ( G̃ m ) and phase margin (φ m ) are specified as 1.5, 4, and 1.047, respectively.…”
