Classification: CPC G | IPC G

Claim 8:
9. A system for controlling a zero order industrial process, comprising:
a Proportional, Integral and Derivative (PID) controller configured to:
receive input data;
generate output data in response to processing the input data;
determine controller error for the PID controller based on an analysis of a measured parameter with respect to a desired setpoint, the measured parameter indicated in the output data;
apply an adaptive gain to the PID controller in response to the absolute value of the controller error exceeding a deadband and increasing, and
apply normal gain, which is lower than the adaptive gain, to the PID controller in response to the absolute value of the controller error being at or below the deadband or decreasing.
