Abstract
This paper examines the implementation issue of PID auto-tuning as applied for temperature control. An exhaustive review of various tuning methods, PID control, anti windup and derivative filters are first reported. A practical PID auto-tuning algorithm is developed for first order plus dead time system. First, PID parameters are calculated based on ON/OFF control. Once these parameters are obtained, the control mode changes from ON/OFF to PID control. The developed algorithm only requires plant output to auto-tune PID parameters. The auto tuning is developed in MATLAB/Simulink and verified for various first order plus dead time systems.
