Claim 0:
1. A method for adaptively tuning a Proportional, Integral and Derivative (PID) controller in a zero order industrial process, the method comprising:
receiving input data at one or more inputs of the PID controller;
generating output data at one or more outputs of the PID controller in response to processing the input data;
determining controller error based on an analysis of a measured parameter with respect to a desired setpoint, the measured parameter indicated in the output data;
applying adaptive gain to the PID controller in response to the absolute value of the controller error exceeding a deadband and increasing; and
applying 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.
