The P-Only Control Algorithm
ABSTRACT: The simplest algorithm in the PID family is a proportional or P-Only controller. Like all automatic controllers, it repeats a measurement-computation-action procedure at every loop sample time, T.
P-Only Control of the Heat Exchanger Shows Offset
ABSTRACT: We have discussed the general proportional only (P-Only) algorithm structure and considered important design and tuning issues associated with implementation. Here we investigate the capabilities of the P-Only controller on our heat exchanger process and highlight some key features and weaknesses of this simple algorithm.
P-Only Disturbance Rejection of the Gravity Drained Tanks
ABSTRACT: Here we investigate the capabilities of the P-Only controller for liquid level control of the gravity drained tanks process. Our objective in this study is disturbance rejection (or regulatory control) performance
