The application of improved immune PID controller in air conditioning control

Abstract The research object is the central air conditioning temperature control system in this paper. Because the control object is the non-linear and large delay dynamic response, we design an improved immune PID controller with the adaptive ability to eliminate its delay time and use the differential evolution (DE) algorithm to optimize the relevant parameters. The improved immune PID controller can shorten the adjustment time, improve the stability of the control system, and have better dynamic regulation characteristics than the PID controller.
