Abstract: In this article, an adaptive PID controller design is proposes for the nonlinear conical tank process. The modeling of the proposed tank process is obtained from local linear modeling technique. Totally five local linear regions are identified and formed to get nonlinear model of the process. The PID controller is designed for each linear model and combined together to get the adaptive PID controller. The identified adaptive PID is presented to the conical system and the measured results are verified with local PID controllers to show the effectiveness of the proposed one. From the measured results, it is verified that the overall performance of the Adaptive PID controller is significantly better than local PID.
