System Identification and Comparison of Ziegler-Nichols and Genetic Algorithm for Moisture Process

Abstract: Moisture maintenance at a particular phase is of primary importance in various industrialized applications such as food processing and pharmaceutical industries. In this effort a laboratory level humidifying arrangement is experimentally tested. A step input was introduced into the arrangement and consequential comeback is analysed. From the comeback, the replica was recognized and validated with premeditated records. For the replica, diverse control strategies such as Ziegler Nichols based Proportional Integral Controller (ZNPID) and Genetic Algorithm (GA) was tested in MATLAB environment. The performance of the controllers based on time sequence stipulations like rise time, settling time and overshoot were studied.
