ABSTRACT:
An electro-pneumatic control system and single op-amp PID control circuit is provided for regulating the output pressure response provided to a load. The control system includes a control valve for producing a control pressure signal and a booster for providing an output pressure response to a pneumatic load in accordance with the control pressure signal. A pressure sensor is further provided for measuring the output pressure response provided to the load and for generating a corresponding feedback voltage signal provided to the control circuit. The control circuit compares the feedback signal to a command signal input in accordance with a predetermined transfer function having proportional, integral and derivative (PID) components, and generates a control voltage signal for stably controlling the output pressure response provided to the load.
