Integral Controller for the Plants with the Asymmetric Dynamics

Abstract

The modification of the Integral controller adapted for control of plants with the asymmetric dynamics is presented. A feature of analyzed plants is that the dynamics of the plant output parameter during the rise and decay is different. The algorithm used in the proposed controller switches the value of integral constant of the controller when the sign of the error changes. This feature enables achieving improved transient performance of the analyzed control system as compared to the case when the classical Integral controller is used. The proposed controller is characterized by higher electromagnetic disturbance compatibility as compared to the asymmetric controllers that include Proportional and Derivative terms. The investigation of the control system based on the developed controller was performed using the electronic circuit simulation program Spice.
