Implementation and analysis of different discrete PI controller algorithms on single board heater system

Abstract

A single board heater system (SBHS) has been developed at IIT Bombay to provide a hands on capability to control system students. In this paper, different discrete PI controller algorithms are implemented and analyze on SBHS using LabVIEW. The PD controller gives faster response, but fails to reject the offset error generated due to load change. The PI controllers are widely used in industries to provide better tracking response. Different discrete PI controller algorithms are described and implemented on SBHS. The analysis of the obtained results is useful to select proper discrete PI controller algorithm.
