Topik: PID Controller; Magnitude Optimum Fulltext: AC021747.PDF (291.4KB) Isi artikel The magnitude optimum method provides a nonoscillatory closed-loop response for a large class of process models. However, by applying this technique to low-order processes, the process poles could be cancelled by the controller zeros. This may lead to poor attenuation of load disturbances if the cancelled poles are excited by disturbances, and if they are slow compared to dominant closed-loop poles. This paper shows that the described deficiency can be suppressed by appropriate modification of the optimisation criterion associated to the magnitude optimum method for PID type of controllers.
