In this paper the adaptive digital control of the pressure process based on PID (proportional-integral-derivative) controllers is investigated. A method for optimization of closed-loop parameters and the continuous-time sampling period of the control system is proposed. The adaptive PID control with optimization significantly improves the control quality of the pressure process, which is demonstrated experimentally.
