Asymmetric PID controller

The controller for plants that are characterized by the different dynamics during the rise and decay of the plant output parameter has been suggested and analyzed. The control algorithm used in the proposed controller is modification of the PID control method. The characteristic property of the algorithm is that parameters of the controller are changed when the sign of the error changes. This feature enables achieving good response of the analyzed control system in case of plants with the asymmetric dynamics. The results of the investigation of the concrete control system based on the proposed controller are presented. The investigation was performed using the electronic circuit simulation program Spice
